Most famous would be.... one that most people remember today. So I reckon most average punters picture a HX/HZ Sandman of any colour really.

Best van however is open to debate, so I reckon it would have to be a custom van from back in the day and as i was too young at the time I have absolutely not a clue. The only one I reallyr remeber was a tough as HR van in street machine in the late 80's. It was candy apple red with a V8 and a flip front. No idea what it was called now though.
