I used a place called "Self Serve Used Auto Parts" in Freetown, MA about 3 years ago. It was a pick-a-part type of place that had domestic and foreign cars, many 200 and 700 series Volvos. Nice thing was that all the cars were on stands about a foot off the ground. Great if you needed to be under the vehicle.

Prices were very reasonable, bordering on cheap! It was worth the three hour drive to the place for me based on the parts I needed, a conversion from an automatic to standard transmission.

Don't know if they're still around though.
