You're referencing the 2nd gen MR2's.
If you want a very "spirited" car, I highly recommend the Turbo model.
Turbo with 3sgte engine=200hp/200ft.lb, compared to the 135-140hp N/A's with the 5sfe.
There's big aftermarket support for the 3sgte engine , but not much for the 5sfe .
The 3sgte engine is very robust and can take a beating. It's got an iron block, an aluminum alloy head and a very strong crank.
Maintenance is like any other car, though the engine bay is a little more of a challenge to work in.
