Are you keeping the e53?

Keeping our '01 for awhile...curious to see the X6, but that may be
academic on price and rear "trunk" room. Not a big E70 fan. Have
another year to go on a WarrDirect ext warranty, so not sweating
it.

I would suspect I need a new serpentine belt in future, maybe
rear brakes. All other systems seem ok, knock on wood. Not sure
I'd hang on to it too long, if I had no warranty support net in place;
otoh, it was paid for as new 6yrs ago, and annual costs are minimal.
