the mr2 would probably be sportier, and the supra would probably be the safer choice... the mr2 has a tendancy to snap overstear due to its mid engine.. this isnt a negative or positive... it just a characteristic of the car, just like many porsches... if it is your first car, it just might be a little dangerous until you get used to it, so if you do get it, try take it a little easy on the turns the first couple weeks... also, i would probably recamend a 93 since the suspention was upgraded to have less tendancy to overstear... some people like the 91-92 suspention better, but the 93 is probably safer... maybe you should test drive to see which you like more...
either choice is a nice car but just my
on the mr2
