I haven't seen a car with a body kit in years. Once in awhile I see a car with a stupid spoiler but that's about it, thankfully the fad brought about by The Fast and the Furious and the idiots it brought in has died down, thankfully.
Hopefully most of the mods unlike GTA:SA will really influence performance when needed and will include some stupid parts or allow decisions that instead of improving performance, hinders it if not damages the vehicle. Hope the thing about excessive over tuning potentially blowing out the vehicle's engine is true. Would be hilarious to see in MP during a race.
