I actually might prefer a pre-facelift coupe to the facelift. Don't get me wrong, the facelift coupe is definitely more modern and the lines flow better, but I don't think pre-facelift coupes look half bad. Especially with an M-Tech II kit. Sedans are another story. Pre-facelift sedans look very dated.
