Hi Kristor,
I was looking at buying a Soarer about 8 months ago, the 3.0lt although the unloved of the 3 models, was the one i was most interested in.
Why you ask ..... if you love the shape of the Soarer and not that fussed with performance or gadgets, the 3.0 is the one for you.
Performance i'm told is about 7.5 sec to 60 so not that bad,and the running costs ( fuel ) should be better than the 2.5tt or V8, the engine is from the supra family so you should be able to get service parts off the shelf.
I got a few insurance quotes but there was no or little difference between the 3.0 or 4.0 models.
What put me off in the end was the running costs of a car that now over ten yeas old, alot of items are expensive to source for the soarer , so weather you need the dash display repaired or new front suspension bushes,your going to have to dig deep into you pockets, if you've fallen in love with the shape of the car then maybe you can live with the costs ,the choice is yours :D .
