I have a 940T. The front leather seats have split in some places. I'd like to either replace them completely or have them recovered. Where can I find replacement seats? Who produces the best seat covers?

 

Junk yard is your best bet, 960's will fit, as well as 740's which last better even if older. Recovering is pricey and looks cheesy unless you pay a lot. What color? Beige lasts the worst, and is hard to find. Black and grey are last well, not too bad to find used. No such thing as "great" seat covers

 

S90/V90 seats will fit too, but are likely to be electric driver AND passenger, so you'd need to run wiring if yours aren't. not such a big deal.

the seat belt attachments vary with the year/model car, but they and the seat side trim pieces, are all fully interchangeable between different versions.
