I won't say it's a steal, but if the maintenance can be verified and service has been performed by a reputable mechanic then you might have a good deal on your hands. Remember that Volvo's like their maintenance and it is normally not "cheap", so verify the service history.

Other posters may have additional things to look for, but I would certainly check the tranny fluid for color and smell. Since these cars have no filter in the transmission, flushing the fluid on a regular basis is a must. If the fluid is dark brown or smells burnt there could be expensive repairs ahead.

These are excellent cars, and if maintained will provide many miles of enjoyable driving.

Good luck
