I don't know what year you're looking at, but I have a 2002 S80 T6. It currently has about 52k on it. I've had lots of new cars of various makes (Acura, BMW, VW, Nissan), and the Volvo is BY FAR the worst new car I've owned. I recently posted about major oil leaks, coolant leaks and steering clamp malfunctions. My car has been regularly maintained and not overworked in any sense. It's possible this car was an unlucky aberration, but I am very disappointed with the quality of the design and engineering of the car (many smaller annoyances since I bought it - e.g., headlights burning out at 5k, software recall, insane climate control system, turning radius of a bus), and also (although not your issue) disappointed that Volvo refused to stand behind its warranty because I brought the car in to the dealer at 900 miles over the 50k basic warranty. Personally, I won't go near another Volvo again once I get rid of this one. My only advice is, if you are set on buying a T6, DON'T buy mine!

Post-1998 Volvos are really not made for shade-tree mechanics.

Nor are 7-Series BMWs.

Consumer Reports has the 99-00 S80 on it's "Used Cars to Avoid" list.

Consumer Reports also has the '97-'99 and '02-'03 7-Series on it's "Used Cars to Avoid" list.

In both cases the cars are relative bargains as used cars because the maintenance costs are so high.

'98 V70 T5 5-speed, 156k mi, front IPD stabilizer bar, rear factory HD bar, Bilstein HD, Volvo strut tower brace and skidplate, e-codes, V-1, Mobil-1 since new, Michelin Arctic Alpins

stay away. The most unreliable car volvo ever built, and it's not just my opinion.
