Not sure exactly what the definition of owning here means as I'm sure we have leases and financed cars in these lists...
I said three. However, I only owned the 2004 330i, the 2003 325i was and the 2007 X3 3.0si I have currently is a lease.
Otherwise it was 3 cars, and it's always a step up in engine power
I must admit the X3 3.0si is the best out of them all.
