Suize has a good point. Pre Reg cars are cheaper too. If you are looking at second hand you could apply to someone like AA or sainsburys and get an excellent rate.

I have only heard bad things about carcraft. Is there anyone you can take with you who knows about cars? I took my retired Mechanic Grandad with me. I was looking at second hand but ended up with an excellent deal only £500 more for a new one compared to a 3 yr old one.
