Help on choosing!

I wold like to buy BMW 3 series Touring,
model year 2002, with 130.000KM on it.

Are there any pointers to watch out for, I realy need to know if there are some gliches on this tipe of model, any know problems with it?
That would prove rather costly in near future?

Thanks a lot.

Tstat, water pump, control arm bushings and window regulators.
