Again, seeing as this is the best thread for boring you lot rather than making a mess of the fleet thread etc...
Impressions after a week.
TL:DR I'm glad I poked you lot and got E46s suggested, big engined ones, and I'm happy with my ragtop, rather than coupe, choice. It's a bigger, chunkier Puma that I can drop the top on to make up for any minor dynamic flaws, and I think I'll have it a while and only make minor, personal, easily reversible changes to it seeing as it's really quite original and in good shape.
Interior
I'm still quite taken aback when I realise this is a sixteen year old car - it feels as tight 'n' right as the Mondeo, which is (at least) eight years it's junior (the original specs would be over twenty years old - the E46 debuted in '97 FFS!) and several generations of CAD/CAM ahead. There are no squeaks or rattles which is pretty good given it's a ragtop, everything feels pretty much spot on (pedal weights, all primary controls etc) and it's hard to find something to fault that isn't 'of it's time' - obviously there's no MP3 stuff or Bluetooth.
The seats could do with a bit of attention but otherwise it's pretty nice inside. The pedal offset is annoying at first, but I'm getting used to putting my left foot further to the right than usual to stop my shoes from clipping the footrest. Everything really does feel no worse than the Mondeo, and some things, like the buttons, feel significantly nicer despite being twice as old.
SERIOUSLY IMPRESSIVE.
Exterior
Still a damned fine looking car, especially with the roof down - the visual weighting is just right. I have to sort the squeaky windows and the condensation in the nearside headlight, but these are simple things.
Engine
Ooh, I can see why people rave about the BMW six pots. At low revs, it's warm hatch quick, or Puma quick I suppose, as that's my frame of reference. Excellent throttle response, and a muted, smooth growl from the back. Take it above 3500rpm though, and it changes into something a bit more punchy, with some real push to it. Get it beyond 4500rpm and it changes entirely, with a muted howl from the rear and a real urge for the redline. All with nary a shake or a rattle from the front. That engine is agonisingly smooth, to the extent where I need to watch the revcounter when pulling away in traffic with the roof down, because I can't hear the damned thing!
I think the mondeo might be faster in some metrics (it does have near 100lb/ft more torque) but I've really missed being able to stick it in third and go from 15mph to north of 80 in one hit and feel the engine turning harder and harder with every 1000rpms, up to a very smooth 6500-ish limiter - I've not bounced off it enough to be sure where it is because I'm not in my 20s any more
Does it drink? Yes, around town I'm not seeing better than 16mpg according to the OBD and that's backed up by tank figures. Eep. Then again, it's a 'big six', and if exclusively driven around town the Puma strugged to get above 25mpg so it's not unexpected. On the run to Scarbs last week I had a low average of about 25mpg, but that involved a lot of high revs for boring reasons, so >30mpg on a run seems quite possible.
Gearbox
Possibly the one area where there is room for improvement. The shift is quite accurate and smooth, but it could do with being shorter and tighter, and could do with having an extra cog. I know the facelift cars sorted the extra cog (I drove one, it didn't feel as good as this, might be down to the gearbox change, or just it being a but rough?), but facelift cars were dogs in my price range, and I don't rate the looks of them as much as I do the older cars.
I'd imagine there are various bushings and joints that can be refreshed at the top of the box that would help, but I've never missed a gear - I'm nitpicking really.
I'm still positive I've got an active clutch delay valve so I just don't rush my changes. I'll get the car up in the air and check that sometime when I can be arsed - I'm not doing autocross in it, after all.
Chassis/handling
Very easy to drive at speed, fairly benign and friendly (if a bit heavy in the controls) in town. Took me a bit of time to get used to petrol engine hill starts again, but pulling away at under 1000rpm (I've seen it idle as low as 650rpm) is now second nature. If I were to never leave town, I think I'd regret not getting an auto....but I do head over to Scarborough and know some excellent roads over that way where a slushbox would be terrible, so I'll take it.
The balance is lovely - it's tremendously neutral, with pretty clean steering, and it very openly telegraphs it's grip limits at each end, even with fairly well worn Dunlop SportMaxxs on the back (in 255/35/R18 - ouch). The handling/ride is well sorted too, almost the opposite of the Mondeo - which has a softer 'large bump' ride but more granular 'detail' (IE you feel more niggles but less speed bumps) whereas this car has a firmer large bump ride, but the niggle traits are better resolved - little things don't really intrude into the cabin much, and if they do, they're there, but muted. Both tread a decent line in terms of compromises, just from opposite perspectives.
What other people think
It's popular in the office, that's for sure, although that might be down to my exuberant driving style. I was expecting to get crap from other people on the road because it's a cocksocket BMW ragtop, etc but with the roof down, in traffic, you let people in/out, you thank people for letting you in/out, you get a smile and a wave back. Perhaps it's only
new BMWs that suffer the affliction of being expected to be piloted by cumstained wanksockets? Certainly, I've had no shaking of the beans at me that I haven't deserved (like stalling it, roof down, music banging, at traffic lights...although even than I gave a sheepish grin and a wave and got a laugh and a thumbs up back) so that's not been a problem, really.
Pootling around gently with the roof down and a smile on your face, I've occasionally noticed people spotting me and smiling back - I think perhaps it might be an age thing (both me and the car) but certainly not had any 'hairdresser' comments or owt. I mean, it'd be ironic....but I digress.
Conclusions after a week
I was a bit concerned I'd have buyers remorse from getting the soft top version, but that's really not materialised. I think to myself what I'd be gaining from the coupe (quieter interior, better detail dynamics, less weight) and then compare that to going out after a late night rainstorm with the roof down and sliding around industrial estates with the engine howling, and I think that makes up for the last 5-10% of RAW CHASSIS DYNAMICS I might have lost.
Overall, I'm really enjoying it. It can do the roof down slow pootle aboot, or you can thrash the knackers off it, and it soaks it up with a playful attitude.
It's like a more grown up, slightly serious, sober suited Puma in a lot of respects (and I know I make that comparison a lot, but it's my main frame of reference and I genuinely believe it's valid) and there is no way that's a bad thing. I suppose if you wanted a broader metaphor, it's like the 40 year old guywith greying hair in a suit who you take out for a sales dinner, have a few drinks, and by 11pm you're doing jaegerbombs, there are suggestions of sourcing class As, and they're trying to set you up with some red haired bulgarian burd.
And I can see why people like BMWs now. I understood it before, but now I *get* it.
What does it want?
Soon:
A modern head unit
Cleaning up of the window/roof seals
I need to pull the headlight that's a bit foggy and sort the seals out
Exhaust flap sorting - probably with a holesaw
Recall work, for airbags I think.
Mid term:
New rear tyres

Choice polybushing (probably around major mount points like rear axle mounts, etc)
A proper wash of the roof outer fabric, which seems to pick up dust and shit. I'll look into that.
A louder exhaust of some kind - it's
too refined.
Long term:
The usual E46 things I suppose - coolant system check (for cracks in the plastic bits - they all do that apparently, and just replacing them is a common suggestion so that you don't dump coolant on the road - a bit like Sigma-engine PCVs, you just do 'em when it's convenient)
Set of winter wheels, ideally 225/40/17in (needs to be 17 inch to clear the brakes) all round to make the rear a bit more accessible

Leather refurb - and lose some weight so I stop stressing the leather
I think I'll probably have this car a while, and as it's in pretty decent condition overall, I'll probably not mess with it much other than quality of life stuff. In some respects maybe I could have got a sheddier example that I could have got my teeth stuck into (stripping out, silly exhaust, big brakes, LSD etc over time) but these cars aren't simple hatch based things that you can pull the head off at home without any real issues, so I think being sensible was, er, sensible.
Long story short, I'm really quite pleased with this.
Right, carry on folks...
