My £200 Volvo was previously owned by the "West Midlands Social Club" and has been abused and beaten to death long before I bought it. I bought it for the price of it's scrap value plus the remaining tax, and solely to drive into the ground for 6 months until I got my Cefiro so it never got any maintenance at all, at least not until the chavs took the Cefiro off the road and I had to actually put the thing through an MOT.
I've since swapped out the engine for one I got for cheap out of an H reg Volvo 740 and it's running really really nicely now. The new engine despite being 19 years old is really smooth, I didn't even have to replace any of the shims to fix the camshaft clearances, they were still all at .4mm after 100,000 miles of use. The guy who swapped the engine for me has a 940 Turbo with over a million miles on the clock.
FWIW I've driven several Mondeos over the years (not the current generation, admittedly, and not the ST170 version) and I'd rather drive my Volvo than any of them.
