I bought a facelift Saab 95 Aero HOT Estate recently, fabulous car for the money. 250bhp+ B235R high output turbo.
The dreaded oil problem that is being referred to is the age old issue of incorrect oil being used and infrequent oil drops; they should be run on fully synthetic oil and if semi has been used an the changes themselves have not been too frequent then a deposit of sludge will build in the sump and block/starve the pick up pipe resulting in a fubarred engine. Mine had a full Saab service history and one owner from new, not to mention v low miles, so it's all documented, but if in doubt then all owners recommend dropping the sump and cleaning it out.
Other things to look out for; direct injection cartridges can fail without warning and mine appears to be the only Saab in the country with all three SID's working perfectly without any dead pixels!
Aero seats are mega comfortable and come in three guises; leather, half leather and 90% leather. They also came with options of motorized seats, heated and air cooled. A range of wheels on 'em, mine are the multi spoke looking 17 inchers.
Very quick, very awesome, very cheap considering you're pulling German superbarge speeds (Clarkson claimed that the 95 Aero is quicker/has more torque than a 911 Turbo in the lower gears) and super comfortable.
