Yes I had the m3 and the 5 series. I part ex'd the 5 series and will sell the m3 privately. M3 is a very good car and I loved it. Fortunately no magor problems during my ownership.
Strong engine and very well balanced chassis but I was looking for something more practical (4 doors) but stil quick enough and reliable. Considered an m3 v8 or an m5 v10 but
the various reliability issues put me off!
