Redundancy and a change of lifestyle are forcing me to part with my BMW 330Ci Sport coupe. I purchased the car, new and to my own loaded spec, in March 2002, since when it has clocked 35,000 miles first on Shell Optimax, then on V-Power and lived in a garage. Although it passed a recent MOT test, I was advised that braking would be smoother if I replaced the two front brake discs that are slightly scored from corrosion. I left the car unattended in the garage (unheated) for a month after a drive on wet roads. Heavy braking won't clear the problem and, I'm told, disc grinding is not an option. Once I've rectified this problem, the car is a fine example. It still smells new inside. Where or how might I get the best price for it?
