Very subtle mods are OK, anything else detracts from what is a fantastic looking looking car in my opinion.
One of the best looking modded (and in general just simply 'best looking') has to be this one:
front-3-quater-view rear-view
Alas it's now in GTV heaven
As for exhausts, I was shocked to discovered how much a modified exhaust was going to add to my insurance policy: £14! And I think come renewal time when you barter the modified exhaust get's thrown in for free.
