My wife is demanding a new Mercedes as her's doesn't have blind spot monitoring and won't slam on the brakes for an armadillo in the road! She wants the over head camera view and the auto park feature. These are about $6k in options --- and complexity (expense) down the road. Bad enough when electric seats or a window button fails. Germany is not noted for long lasting electronics --- but as bad as Lucas (The Prince of Darkness).
Ok - I'm somewhat embarrassed that I added and backup camera to my newish Miata. Head won't turn that much any more. Thinking of adding a front one too so I don't bend up the front air dam.
