Hey mate- Yeah I have owned a Soarer (91 JZZ30 so it was the twin turbo version) as well as a NA MR2 and currently a turbo MR2
In terms of 'driving pleasure' the MR2 wins hands down- It is a more involved car- better steering and handling, better seats and a more 'snug' cockpit.
The Soarer is very different but still a great car.....it is superb for longer journeys and for cruising- lots of power, luxurious interior and a bit more space etc.
My non turbo MR2 never felt 'slow' but you did have to work the engine a bit harder compared to my turbo MR2 which you can just use the torque- There isn't much point going up to the redline as the compressor is a bit overwhelmed and the 3S aint no B16 in terms of reviness
.
In terms of work costs on the MR2s- Labour is usually what becomes expensive because they can be hard to work on. The soarer is pretty easy to work on comparibly- everything is in easy reach but parts are probably more expensive (although I had a good run with mine- Just normal 5k oil changes etc). A 4G Soarer will probably need a lot of fixing up though....
So it depends what you want- I would suggest, in your situation, that a non turbo MR2 will still give you the thrills and use a bit less gass etc but check insurance because it WILL be expensive for any of these cars. If possible, the NZ new N/A Mr2s are the pick of the bunch if going for the early nineties ones as they have no power steering and probably a better service history (later ones are usually above 4g)
