VW are rarely there in their own right. The only time I've ever seen an official VW stand at the NEC was the year they launched the GC. Occasionally you will find a Cali Ocean on the rental folks stands but never seen a GC. You will see VW Crafter/Man TGE base vehicles from the converters and big name MoHo brands. If a GC is on your list best to go to a VW Commercial dealers first and get a good look around the 600 and/or 680 then go to the show for comparison with the other makes.
