Although kind of hard to find used, since no one who owns one seems to let them go, I found a 1994 940 with 147K on it for a fair price and put $1000 into it to get the full 30 and 50K service done on it. I fully expect to have no problems with the car for 3-4 years now, beyond typical maintenance, as these cars are solid, safe, comfortable and reliable. Repair labor and parts seem about the same as my Honda and used parts abound, at least in Portland, OR, probably the Volvo (and Subaru) capitol of the US. My minor quibbles: the air conditioning is not the best, even though I have a newer compressor and the sound system/speakers are not that great, even after I installed a new CD player.
Overall reliability, easy, basic engine that is simple to work on, comfy seats (with seat warmers), decent enough mileage, big trunk with split back seat for hauling stuff, sportier, less boxy than the 240 model, although it's basically the same car.
Better sound system, more reliable air conditioning.
