How you guys doing, i'm now in the market for a car and my decision has come down to this two options, i have done "some" homework and im aware of the obvious differences among the two, Mainly power on tap, back seats ect... pricing they are some what close to each other as well in the pre own sector.

but has anybody own both at one time and know what would the cost of ownership would compare (gas, maintenance) how are they both equally reliable? repair costs? or would an M3 compare more to a 911?
I'm aware i would get bias answers here but lets hear your opinion.

thank you for your time

 

bmp any ideas ?
