I have absolutely nothing against front-drivers, on the contrary, I appreciate them for characteristics that they possess and rear-drivers do not. Don't mistake my reluctance to believe a Spirit is unmatched and incomparable merely because I pointed out a flaw stemming from it being front-drive for a dislike of all front-drivers.
I think an M3 can outperform a Spirit. That's very specific, and not at all the generalization you make it out to be. Furthermore, it just so happens I'd take a Spirit over an M3 in an instant solely because of the "not a BMW" factor, though I'd take just about anything over an M3, so that's not saying a whole lot.
I don't know this. It may be faster overall because I know E30s aren't geared for top speed, but because I don't have the slightest idea how a Spirit is geared, I won't make any bets that it's not actually slower. I certainly doubt the Spirit's acceleration prowess over the M3 because of exactly why I said; being front-wheel-drive (and don't confuse this for hatred of front-wheel-drive vehicles), hard acceleration and the subsequent transfer of weight to the rear of the car will drastically reduce grip to the driven wheels.
It has 30 more horsepower than an E30 M3--got it.
