I parked a MK2 Octy next to Mk3 model at a dealer but I couldn't see any difference in the length between them. I thought the Mk3 was meant to be 10cm longer? The MK3 maybe wider but it has smaller wing mirrors that don't look like Dumbo's ears like on the Mk2, so that cancels out alot of the extra width of the body.

so that cancels out alot of the extra width of the body.

Unfortunately, it still counts very much in the average supermarket parking space - more likelihood of being 'doored' :|
