I dealt with him recently.
A "proper" dealer in my book. No worries.
+1 I bought my car from Dave Randal too.
Dave supplied the names and contact details of the previous two owners for me, so I could speak to them and get a detailed car history before buying.
We then agreed the price and what needed doing (including a service, fitting a luggage rack, personal reg transfer, etc.) and all was done ready for collection at the allotted time, no problems at all.
He recently completed the paperwork for a new agreed valuation certificate for me for the insurance as well.
Top bloke... IMHO.
