I bought B7 Audi RS4 from SK Performance in Bolton. Hassle free, good price and nice guys. Agreed a price, test drove and put down my deposit. No problems. Also no messing around in getting the car ready for me, it was ready to collect when previously agreed and I traveled the 300miles down to Bolton to pick it up. Please however be weary of the 'warranty' they offer... this is a 3rd party warranty and (at the time I bought anyway) was worthless... couple of small issues a few months later (parking sensors) and the warranty company basically told me i've no chance of getting the cost of repair covered. Disappointing but maybe I should have looked it up beforehand. Bear this in mind if taking a warranty as part of negotiations on a car. That aside, I am happy, i got the car I liked at a price I liked and would buy again should they have a vehicle in that i'm looking for at the right time etc... (i'd just exclude the 3rd party warranty or discount it from negotiations) 4/5.
