You may have managed to negotiate a better deal, but as someone else said above IMG and SEAT Stockport were the same cost (for what I wanted) but Stockport don't charge an admin fee so I went for them.
I was getting an ST but it looks like IMG are slightly cheaper for the 5 door. Regardless, there are some crazy good deals around. I was almost going to get a GTD...
I'm now really hoping it arrives during June else I will be carless for a while.
