I'm calling BS. BMW owners don't change their own oil. They pay proletarians to do it for them.
After working on all makes for the last 20 yrs I have to say that all of the european cars are basically over-engineered junk. Somewhoe they manage to make everything more difficult to work on, and at the same time make the parts out of recycled beer cans and once wetted newspapers. The interiors are crap, do not last and have some sort of shitty rubberized paint that flakes off if you look at it funny. These are cars that are 4 yrs old and have 60k miles, not old dinosaurs. Ford and doge interiors hold up alot better, as do the japanese cars. Koreans are getting there.
Volkswagens are the biggest pile o steemin' poo that ever was deposited on the earth. BMW is not too far behind, with Mercedes. And volov and saab make snap-tite cars, try taking anything apart without some clip or fastener breaking. Jags are turds, although they are better since ford bought them.
