I bought a 2007 c70 for my wife just before the first of the year. It's in good condition, purchased from a Volvo dealer, and my independent mechanic gave it a thumbs up for the usual mechanical problems. When I drove it around for an afternoon before committing, I noticed that it was a bit noisier than a sedan, which was not really a surprise given the design, and my s60 has spoiled me for sure. There were some rattles and creaks from the top and the trunk area when going over bumps with the top closed. That was a rainy day in the mid 40's, and my main concern was that there were no leaks or mechanical problems with the car. I ran the top up/down several times, checked for signs of rubbing between parts, it all looked good.
After driving the car for a few weeks, and in much colder weather (high today will be 16 F if we're lucky), I'm hearing some pretty loud thunks in addition to the creaks etc. The noises come from all around as the top flexes, a bit disconcerting really. Granted that some of this is due to ice buildup on the body, hard, low profile tires in cold weather, and the roads have really suffered with numerous potholes etc. What I'm wondering is, how much of this is normal? I always liked the c70 but didn't ever expect to own one, so most of my research has been after the fact. I don't see reviewers complaining about noises or rigidity problems, quite the opposite really. But, with the age of the car I wouldn't be surprised if there were some nuts and bolts or bushings that need tightening or adjustment.
Not too many posts here about this car, likely due to lower volume than other models. Any 2nd gen c70 owners care to share their experiences?
