MK5 Definitely not underrated. Has its hype around the car scene. Its a beautiful successor to the MK4 it only gets hate for having BMW internals which I think people are accustomed too it by now
The A80 is overrated like the Buick GNX is overrated. they're both rather anemic in stock form. The A90 is overpriced. You are paying for the Supra name. Keep in mind that 3 liter straight six is the M4'/M3/Z4,s trophy.
