The biggest question should be how the car was maintained. I doubt a 428 owner would care about the car enough to go extra mile to maintain it. BMWs serve long with preventive maintenance and die quickly if maintenance is ignored.Scanning is not my only concern. My main concern is these cars appear to be throwaway cars designed to last ten years or 150,000 km's. Kind of like the phone market...planned obselecence. We are also looking at Audi A4's. The 2012's we've looked have rusted undercarriages and even fenders.
