I fully agree to the above statement. Buy BMW at most visit the
workshop a couple of time more than the Lexus, you need to face yr
wife everyday !!!! 
If finally you cant tahan the nag and change back to BMW, you loose
big time. Might as well go for the BMW.
The decision got nothing to do which car better in drive, in comfy,
in value, better power, handling or whatever. You just need to
avoid domestic problem.
