I've been looking at this recently thinking about a change, The issue is, the Supra despite the raise in prices, is still allot of car for the money.
The ones I had been looking at are the following at around the 30-50k mark
GTR- Epic performance but GTR maintenance is a bit painful
Audi R8- problem is your in early V8 territory not the v10
Aston V8 vantage- lovely cars but a very different car, and cant help but feel its a bit older man for me, however im still tempted
Porsche 997 911- in the peasant spec price tag unfortunately not the turbo car.
Ariel Attom- Just pure fun but pretty much unusable for anything other than a short hoon.
Ferrari's- this is a bucket list item for me but again just not going to be getting a model you desire imo. Was tempted by a 348 at one stage but its a bit to old for me, I still want a 360 manual car.
Really depends what type of car you want and how far you can stretch your budget.
