what blows me away are things like one of my wifes co workers BMW. it does not have a oil dipstick. it only has electronic one. Also the oil drain and fill are simlar to airline fitting. only really BMW uses them, so for example you can't even change the oil on the car in your drive way...
Doesn't BMW give you free oil changes for 100,000 miles? I would bet, since their demographic doesn't include do it yourself type of buyers, they do this to prevent operator error during the warranty period. Either way, if you can afford one, you don't really care what it cost to maintain one.
As far as Lexus, it's just an expensive Toyota ain't it?
