I got a fully loaded one with Leather Recaro's and Xenons etc and i love it, true it's not the fastest car in the world and i have 19's on mine which kinda hinders the speed thing but i don't really drive it hard.The money you ned to spend on engine mods compared to what you get in performance is not the greatest either but just the same a lovely car.
As said before i would go for a MK1 RS before an ST.
