Regarding depreciation and build quality, just over a year ago my 159 2.4 Q4 SW was written off in an accident and the insurance paid out what Id paid for the car.
As I couldnt find another I decided to pick up a 5 Series Touring as they are plentiful and therefore cheap until I found another (still looking). Both are/were 2008 cars and its amazing how the BMW feels utilitarian, like a tough industrial item, and not as solid as the 159. This has been born out by the constant repair bills Im having to fork out on it - a grand on a new wiring loom last week, is that normal on a 4 1/2 year old car? I dont think the new engine at 85,000 miles is a strong recommendation either.
In some respects the BMW is very impressive, the suspension still feels tight at 112,000 miles and its a really well thought out car. Touches like the opening tailgate glass, ability to clear speed humps without grounding, built in retractable dog guard and cup holders that arnt in the way of the gear lever are make it good to live with but it is soul less and I feel sad every time I pass a 159.
My plan morphed from hunting another 2.4 Q4 to waiting on the new Giulia but Ive lost so much faith in the 520d that Im scouring AutoTrader for a regular 2.4 Ti SW before anything else breaks on it but have only been offered £6000 in part ex, which again is a let down for the German
