drive it 30,000 miles per year 100% on free supercharging for 8 years. Assuming $3 per gallon on premium gasoline and 20 miles per gallon mileage, the fuel cost saved in 8 years would be $36,000. And oh, how much you paid for your M3? $25,000 after rebate. So the chance you actually making $$$ by keeping it longer or driving it more is quite good. MS and MX can't achieve this for their owners because their prices are too high. So anyone out there still can't make up their mind about dropping $1K for order one on March 31?
