I don't hold the opinion that everyone's Volvo is in perpetual need of repair.

Maybe a simpler question might be ..

"the brick that you have those gremlins in - did you buy it from a po that may not as been as good at upkeep as should be?"

or

"the brick that you have had for years (maybe since new) that you have babied and kept up wonderfully - has it started developing hard to solve problems just out of the blue?"

The first is understandable. The second may have a common thread - like ground points oxidizing; weather more severe in certain parts of the country ..etc.

I generally have the idea that these cars can go on forever (unless you get rear ended like I did in my 745 (RIP - snif, snif)
