I took my sister there to replace her car. She went for a vw polo. Quite a lot to choose from and as you say,the test drive area around the street is not the best. The price was about right but we had to sit through a sales pitch trying to get her to add a wax to the out side and a treatment to protect the seats.
Boring and I think a waste of £. One thing I did notice, lots of the cars had the valve caps missing? I would use car giant as place to start looking just to get an idea about price etc. She had the car about 9months and is happy. You do need to check who had the car you are looking at. Lots we looked at came from people who had special needs so check the log book. For the life of me, I don't understand why all the cars only had the very min amount of fuel in the tank, so much so that the test drive person we went out with was a bit concerned that it could run out! Every car was at empty and even when you pick up your car car giant say that you should get some fuel ASAP. The sales operation is slick and quite smooth, don't think they take c cards but could be wrong, best to phone or check before you go.
