I just purchased a new (to me) 1994 940 for my (almost) 18 year old. He is enamoured with the car and a great future BrickHead.

I have been away for a couple of years (previously owned an 89 740 Turbo) and it is great to see the BrickBoards alive and well and, as ever, extremely useful.

I have three questions:

The car comes stock with 185/65/R15 tires, but mine has 205/60/R15 tires on it. I am going to go back to the stock listed tires (can easily be persuaded in other directions by input from this board) but want to know if it is likely that the 205s are still on stock wheels, or, did they likely change wheels as well?

The car has the cloth (light brown) interior, excellent condition, except that the left side of the driver's seat is somewhat torn loose from the seat frame and the foam is very soft. Are the upholsterers out there? Is there a reasonably priced replacement seat? Anyone ever tried the pairs of "racing" seats as seen on ebay?

OK, the real issue, the car is somewhat sluggish on acceleration. Especially if already in fourth (or overdrive?). When I bought it, it definitely knocked or tapped when trying to go up a slight incline and maintaining 60 or trying for slight acceleration. I changed oil (Rotella 5W-40 full syn) and the knocking is now almost non-existent unless really warm and trying to push above 70.

I expect I will do a tranny flush shortly, but want to know where to look for other things that might improve the acceleration.

Thanks in advance.
