Only modded xd's I've seen around here are a beige sedan (I think a member here with 17's and h badges replaced at taco bell) a black hatch with 17's and exhaust with a black girl driving, 2GTS driving up the hill at Four Lakes while I was waiting at the light, and a silver sedan with 17's and some kind of exhaust with pennsylvania plates. I saw a black sedan with out of state plates and a glass pack a few months back.
Mine's not really modded anymore, I took my intake out until I get it to the dealer for some stuff. But I always try to play with Elantras with young people driving around here.
