I have had my X5 for about 8 months.
It has been everything I had hoped for:
fun to drive and comfortable.
Everything is solid. Not a rattle or
other problem (knock on wood). The
paint job has been particularly
impressive. I have taken a lot of rock
hits at highway speeds, but I have not
yet found one chip!
The 360 degree doppler, after taking
some getting used to, is very handy
parking in my underground garage at
work. Love the auto-dimming mirros.
The sport seats are great.
My only complaints are minor. The fuel
consumption is nothing special for a
3.0L (about 18 mpg) and the dash blower
on the HVAC system is surprisingly loud.
