Exhaust joke is getting a little old, but yeah they are a mess...
Exhausts and sidevents actually suprise me. Entering the market first time, that was quite an ambitious move. Lexus obviously see aggression in the M3 and RS4 and thought they could try it in their design. Obviously it didnt work perfectly.
It's not all bad though. I like grille and front bumper despite being subtle. The paint, wheels and spoiler are great too. Interior looks not too bad either.
I'd take the E90 M3 or RS4 over this any day, but the M3 still has tacky things too. Look at the mirrors from front view, power dome & hood vents, side vents and rear diffuser. Interior is also just like the stock 3 series. Let's not forget the fact that BMW are confusing us by puting the Coupe front on the Sedan.
