Dude, that's a tough comparison, a rear drive mid engine turbo car versus a front drive all motor car. I would have kept the MR2 but it's too late. Try this on for size, a vtec with a turbo.
Seriously, I'm a Honda fan since I was 16 and old enough to drive, but Toyota makes a nice product too (my wife's 93 Camry has 152000 miles on it and drives like new)
You will definitely miss the way that boost comes on rapidly and the resultant surge of power, but most factory turbo cars fall on their face at high RPM. Not the ITR, this car was born to rev, and just as the turbo was fun at low rpm, the ITR lives to rev above 5500 rpm. You will get addicted to VTEC just as you were addicted to boost.
There is nothing like blasting by someone at 8000 rpm, with their windows rolled down, it's like getting pimp slapped by VTEC.
