I've owned two 850's, one N/A, and one turbo. They have been more reliable than my old 240, if reliability is defined as a) things breaking while you're on a long trip, and b) how much do you have to fiddle with it to keep it running right. Neither of 850's ever left me stranded as my 240 did, twice. Yeah, 850 is more difficult to work on, and more expensive, but I have to do it less. Plus, the 850's are more comfortable, quieter, and to my mind are more attractive designs.

Not to say I didn't like my 240, I did. It was my first Volvo, and I look back on it with fondness.
