I purchased a first car for my daughter from Car City Luton last month, and the experience was a positive one. Despite the car (a Fiat 500) being a less prestigious one than most of the cars on the forecourt I was treated with courtesy and professionalism.
There were no attempts to gloss over any issues which needed addressing; all points were attended to within the time promised, a fair price was negotiated without unnecessary haggling tactics, and I was allowed to collect the car in the evening in order to surprise my daughter on the morning of her birthday.
She was thrilled, and a subsequent after-sales issue was also dealt with promptly and without fuss.
Car City won't get rich on my purchase of a 6 year old Fiat, but based on this experience I would buy a more valuable vehicle from them, and am happy to recommend them to others.
