Since I sold my original mk1 in 2010 I've had various cars, including both a mk3 and mk4 Supra. I loved both of my Supras, but in terms of flingable fun I couldn't resist the draw of returning to a mk1 MR2
I can't comment from personal experience of track use (although that's set to change at the end of this month!) but there are plenty that exist as very potent track toys. Best bet is to see if anyone near you is willing to take you for a run out - if you're ever down in south Oxfordshire I'll happily give you a passenger ride
