How's the S60? Does it have any electrical problems? How about the handling? I think I'm a bit paranoid here, but Volvo's seem to have lots of electrical problems, and they are more nasty than the ones German cars are experiencing (i.e., Mercs, BMW's, Audi's)
It's too curvy.
The S80 is too expensive. Its around $50K+ USD with options which puts it in the same range as a 5-series and Audi A6. As far as reviews go, they say it looks nice inside and out but the driving experience is (predictably) lacking.
