These cars are bullet proof,
I bought my 2011, 320d LCI with 83000km on the clock back in 2015,
When I sold her last year she had 231000km on the clock (I do about 35000km per year),
Only maintenance I did was servicing the car every 20 000km's, 1 x set front shocks, 1 x set rear brake pads and 2 x sets of run-flats.
