I bought a car in January from Big Motoring Word. We are now in November and this car has cost me £1600 in repairs. Yes, and this is with one a one year extended warranty. They fit inferior parts and avoid responsibility at all costs. After picking up the car and driving home the warning light came on. Nox sensor faulty and condensation in headlight. Replaced at BigMW which failed after a week, condensation issue ignored. I had the Nox sensor replaced by an independent garage with a manufacturers part. BMW would only cover part of the costs. The condensation issue eventually caused the headlight and control unit to fail. BMW extended warranty have said take it up with the garage that sold the car and BMW After Sales have said its too far after the purchase to deal with it. Not a company I would recommend. Avoid at all costs.
