They have to head off on business for a week and have a temporary garaging challenge. You have a garage with space, and agree to look after it for him/her for 7 days.
Car is dropped off. They stress that you must have a shot - it's incredible.

It's late-January, and the full week is completely dry, but the temperature is hovering between 3-5 DegC every day. It's on pretty extreme summer/track tyres.
You live on an awesome, relatively quiet "drivers road". Fast sections and twisties.
You have a helmet and suitable clothing, fit in the car without issue, but you are only insured 3rd party via your own car insurance. It would cost £25k to get you insured on it - doesn't make sense.

Your friend confirms they are more than happy for you to take it out on a "you bend it, you mend it" gentlemens/gentlemanandgentlelady/mates verbal agreement.....

NOTE: for this imaginary scenario you may exchange the Mono for a very rapid car of your own preference around the £150k value zone.
