Just purchased a used VW Golf convertible from Quest and am extremely pleased with their customer service and the whole process. Quest seem to only stock high quality used cars which I think are very competitively priced – my car was immaculate inside and out and a complete service history was backed up with a very comprehensive mechanical check, full service, 12 months MOT, and 3 months warranty (which we extended to their 2 years cover for a very reasonable price). Attention to detail and customer satisfaction was excellent and the very few minor items such as small paint chips were addressed as a matter of course. Lots of used cars out there ....... but why risk going anywhere else.
