Drive the M# for a few days. I found riding in one very uncomfortable. The seats are hard and the ride is harsh. On the M3 I was shocked to see to poor build quilty on the one I drove. ( a friend's). When it was relatively new the drivers door would not open (plastic handle defective) The interior plastic crap was falling apart. I thought about a BMW but I'm too cheap to let someone else do the maintenance like valve adjustments which require expensive tools.
