Bought a used Golf in January from Marshall's Newbury. Picked out some remedial work including 4 damaged wheels and valet that needed doing to agree a deal. Deal agreed and to include having 4 wheels diamond cut to original standard. 2 weeks later i arrived after a 3.5hour train journey to be told that there is a fault with the car. Car was left for them to repair and the agreed to deliver. On the day of delivery, found car had not been valeted, all 4 wheels patched up with silver paint, and nearside sill damaged from where the alloy wheel repairer has jacked on the sill. After reporting this, it was agreed i would have the car valeted and Marshalls would cover cost have having the wheels diamond cut as they should have been. Wherls have been with the refurbishers for 3 weeks now as they are awaiting payment for work to start. Multiple phone calls and emails saying payment has been processed but still no further forward. In essence the used car preperation is poor and aftersales is disgusting. Since buying the car in Mid January, the car has only been on the road 1 week and still awaiting Marshalls to sort out the issues i have. Beware when buying from Marshall Group.
