When I was first looking for a diesel. I looked at a Volvo. I called a Volvo mechanic and they told me to run away from it, not walk, run. They do have a VW diesel engine. It has an aluminum head, which is prone to warping when overheated, just like the VW's. From what I hear they only last around 150k. The timing belt is on the backside(firewall side) of the engine, which looks like a real PITA to change.
