Matt,
We didn't have one V70R. We had TWO.
We bought a new 2004 V70R in July 2003. The list of problems with that car was long, many of them common to all. It did end up with a boost problem in the fall of 2004 that Volvo couldn't fix. They sent two factory techs down, two different times, and both failed to remedy the problem. After it was in the shop for 1 week it had already exceeded the lemon law requirements based on all repair time the prior 15 months. We waited another 2 weeks and still no fix.
Hence Volvo came forward with an offer for us to sell the car at wholesale to the dealer and they would sell us a brand new 2005 model at dealer cost minus $8500. In net we were out about $4k on the 2004 after driving it for 18k miles.
We ordered the 05 model, but this time we ordered the 6spd manual (the auto tranny version was a disaster in many ways -- Volvo limits the torque output substantially, limits max rpms in 3rd gear and higher to less than peak HP rpm, etc, not to mention it was impossible to drive smoothly due to horrid throttle-by-wire programming). The 6MT wagon was a blast to drive when it was running properly, well, blast until design problems reared their ugly head. Some here may remember me bringing it to VIR a few times back in 2005.
I won't continue the list in this thread hijack, but the 2005 was back at the dealer at 800 miles with the climate control system dead (bad electronic module...ok, early life failure, no problem), and that was just the start of yet another round of issues month after month.
Oh, did I mention the fuel pump failure that stranded my wife on the road? I don't think she's ever been as mad at a car as that day, and I don't blame her.
Call me if you want to discuss more. There are design issues too that you might find less than desirable.
