What would you do...?

2A for me.

M3, great car, fun factor is high especially since you are coming from a boxster, enough back-seat space - unlike the 911 - relatively low mileage for a two-year old car.

I was never a bike lover, however I see your passion but as you mentioned with the high gas prices I would reject this option.

The other cars are fair choices but the M3 as an overall package will provide you everything.

Second choice is the 911 as long as you are willing to take the risk without warranty on it and you do not mind the "fake" 4-seats!

Whatever you do good luck!
