Absolutely nothing, not a sausage. Totally reliable!
Glovebox rattles (really annoys my wife!), sometimes 3rd gear is difficult to get into (rare).
Apart from those very minor niggles, it has been a brilliant car, very solid and safe, fantastic cruiser on motorway, much smoother at 100mph (in Germany!) than our previous 318i, and noticeably quicker.
With the electronic controls, one of the best dashboards I've seen on any cars, apart from maybe Lexus, or the new Volvos. Steering is brilliant, very precise. Ride can be harsh over bumps, but it is a drivers car I suppose.
Passenger space is cramped with 3 in the back, and boot is awkward for luggage etc.
Definitely recommend this car to those who enjoy driving.
Really want to see the new model, to see how they've improved on a great car!
BMW 323 is actually a 2.5ltr.
The 323i is the 2.5 engine. However it has about 25 less BHP. This is because it has a different manifold, exhaust and ECU.
