Sump gasket went, £250, beware it has 2 sump gaskets!
The best car I have ever sat in. No one knows what it is so you can pull up next to almost anything at the lights and leave them standing! 0 to 60mph is 5.7s, quattro system gives great road holding, looks a peach and is as safe as they come - I managed to put it on its roof on the M6 and get out without a scratch, unfortunately the car didn't come off so well and they are so rare - 279 ever sold in the UK - that they are hard to find in good condition.
Get one before its too late.
Thanks for your review.
I drove a 1991 S2 some years ago and found that the Bosch Servotronic steering was so awful it was like driving a bad arcade game - far to light and absolutely no feedback. I heard that this was deleted in 1994 (I think - at the same time a 6-speed gearbox and 230bhp upgrade was introduced). I wonder if any upgrade owners have any comments about the steering quality of these later cars.
As an owner of a servo assisted S2 (1991) I can tell you that its very easy to remove this and go back to standard power steering. Just simply unplug the control unit for it which you can find under the back seat on the right.
