Personally I think id spend it on several options. You can get a lot of 2nd hand car these days for not a lot of money.
20k Audi B7 RS4 - Id have to keep it, it ticks all the boxes. 4 Door, Rapid, V8 noise, prescence, relative rarity, 4wd.
10k - Impreza P1 - From the day I walked past the Subaru garage at 16/17 and saw one in pride of place in the windscreen I wanted one. Classic nutter lads car. Could use it for the track as well. If they hadnt all been raped and barried to death id have one now.
25k - BMW M6. Never owned an M car, might as well make it a 5l v10. Could get a decent prev gen 2nd hander at 25k and id probably make it a convertible to have a convertible in the garage.
15k - RangeRover Sport - Greenlaning and general lording it about, get an 05/06 easy at this price.
5k - Jaguar XJS V12 - Used to have random dreams about owning a Red one, no idea why. Good for when im really old.
15k - Caterham 7 - For smashing round a track
2k - Ford Puma - Had a 1.7 as a company mota for 3 years, loved it, good looks, relative economy, great to chuck about.
2k - Mini Cooper for the mrs. She has a pants car. She'd be happy with this
6k left. Which tbh Id need for petrol!
