Hi Mark,
I think you're talking to the wrong crowd if you're looking for a go on the MR2... The people who sit here and read these posts are probably also in therapy over our 914's.. we just love 'em..
I'm somewhat biased on the MR2 turbo.. my roommate works for Toyota in Torrance.. he owns a 95 supra twin turbo.. the turbo is fun, and it's definitely fast.. almost scarry fast, but i'd take my 914 over it any day..
in the end.. it's really your opinion.. drive them both.. and make the decision yourself...
good luck,
Jeff
