Someone needs to contact WatchDog and get them to do a story on this cowboys. With the amount of people that have commented with bad experiences on this thread i'm sure if a Mod sent it to BBCWatchDog they would look into it and see if its worthy of a segment on their show.
Also i'm surprised customers havn;t taken Big Motoring World to Court. Theres no way i;d stand for this sort of stuff.
I;m so glad I did the search on google before I went to these guys when I was looking for a car.
