I know some peeps have been claiming that the i8 isn't a really a sports car and that it's no match for the M3/M4...well I think you'd better reconsider:
0-60mph: 3.8s (quicker than M4)
1/4mi: 12.4 112.1 (same as M4 but lower trap speed)
MT figure eight: 24.6s (faster than a Alfa Romeo 4c)
So it's quick and it can handle. And it's lighter than a M4 and of course it gets great gas mileage (which I don't really care about). And it looks MEGA epic. If you had the money why would you pick a M4/M3 over the i8?
Also I drove a F-Type R (like the one in the beginning of the bid) and it was FCKING AMAZING. Wicked fast and sounds liked sweet thunder. The best part is when you lift off throttle and there's a procession of crackles, pops and overrun. Not sure I ever smiled as much in my life as I did when I drove it in a tunnel.
