Every now and then, my Volvo breaks in some annoying little way... like the wimpy cupholders that slide out from the console lid, packaged like origami and about as strong.
I have two places that I usually use to buy replacement parts from, and neither one is the local dealer, who has a healthy mark-up on his parts (although they do have nice free breath mints and chocolates at the service counter).
The first is an outfit called FCP Groton, at www.fcpgroton.com. FCP has a good selection of tune-up and wear-out parts for Volvo and a number of other European nameplates. The prices are very good.
The other place I have been dealing with is www.getvolvoparts.com, which is an e-commerce site for an auto dealership in Rhode Island called Tasca Automotive Group. When I needed a secondary air valve recently, Tasca had a great price, and very friendly service. If you need help, you can call or email them and they will support you. Tasca has a very nice online parts catalog, where you can find just about any part on your Volvo.
