I bought my Zed from these guys. It was a mixed experience. The first guy I dealt with (Sean I think) was pretty helpful and was pretty accomodating on tidying up a few bits and pieces on the car which was done.
I did take the risk and put down the deposit without test driving on the promise of a full one on pick day and a full refund if anything wasn't right. I ws a bit hsitant about this, but in fariness the car was completely blocked in and would have taken ages to get out and they were very busy that day.
When I went to pick up I dealt with Steve. Didn't like him one bit. He tried to wriggle out of letting me test drive it, but I insisted so he relented in the end. When I got back and said it was fine he was pretty much 'I told you so'. He was pretty discourteous through the whole process, treating me like an annoyance rather than a valued customer. Also, after I had paid, he told me that there is no manual with the car, because he'd given it to someone else who'd picked up their 350 that week. At that point I was too excited about driving home to kick up a fuss but in hindsight I wish I had.
Overall I'm glad I bought the car, it hasn't missed a beat and I think I got a good price. I'm not sure I would deal with these guys again though, purely from my experience when picking the car up. To be honest if I was the owner and reading this thread I would sack Steve on the spot, he seems to be the main problem.
