which would you rather have?? the E30 is lighter and more like a go kart on steriods. the E36 is more powerful but heavier. still a fast car but the E30 is a better track car. the E46 is even more powerful but even more heavy. i'm not sure which one i would take. the E36 probably looks the best(IMO) but the E30 is a better track car. the E46...i'm not sure what its best at.
