1st off all, dont think that all 21 year old "chavs" are chavs!! im just 22 and i LOVE my car standart looking!!
2nd i know a few late 30's gentlemen that can be more chavs than you can think off!!
and 3rd if you are in the lights bussiness, i really think that you could wast our 2k on neons and sh*t like that on your car, after all you are looking for a promo car for your company, right?? it will look spot on!!
and just to finish, if you are so lucky to have loads of money that easy, i say what other members have said before!! do a proper service to your car, invested in better brakes and if you are looking for a nice engine with nice power output... so single and polish every bit that you can see!! and job done!! get ready after that to waste your money again in a engine re-build because that internals will not be up for that amount of power!! as you can see there is loads of staff were you can throw money in!!
result of this will be: nice promo car for your company!! nice engine and full of lights!!
