well, i think some little modifications , as muffler, filter or chip tuning are good if well made, they could bring some good results in power and weight, because the factory must pass restrictive omologation parameters (emissions, noise,...)and nothing sounds better than a "free breath" lambo

major engine modifications could also be good IMO, but they requires attention and money, more the handling colud become seriously difficult and you
must be carefull.... driving this kind of car

for the line it is very difficult to improve the beauty of lambo design but sometimes...it can be done
