What doentations hv 2 b gven 2 buy a car?

All dealerships are different, the main agents will want to take copies of insurance and full driving license, your local garage may not be bothered about seeing anything other than the cash so you could just drive away uninsured without a license. As you are a new driver you would in my opinion be better buying an old car privately as most new drivers bump their cars within the first 12 months, once that is out of the way buy what you want with some experience under your belt.
