I am considering buying a 2006 s60 2.5t it has 103k miles and almost everything is in great condition, the problems are that it vibrates while in idle but after accelerating it immediately goes away. Also there is a light on that says srs airbag service immediately. The carfax shows no report of accident. Other than it drives runs and sounds great, the asking price is 6495 is it worth the potential troubles? Any help would be great thank you.
