General Comments:
The car is very solid, well made, quiet and good to drive. The interior and exterior are in showroom condition, considering the car is 7 years old. The materials used seem to last very well, particularly the seats and carpets. There are no rattles or squeaks, and everything feels like it will last for a long time to come.
Bushings seem to be a major weak spot with these cars for some reason! They are not expensive to buy, but BMW labour rates are ridiculous (€115 per hour plus 21% VAT). The seal on the differential was itself €20 but cost €280 to fit, and this could only be done by BMW due to the tools required. Resistor on interior fan is a common problem, but again pricey to repair.
The car is good to drive and very refined. The engine is extremely smooth so can be revved, but it's a bit flat until you get it to about 3,500rpm. Performance is fine rather than great!
MPG-wise, I am getting late 30's on a long run, and averaging about 32mpg, which is not bad considering I have a heavyish right foot!
