Height: 147.6cm (2008 VE Omega) Width: 189.9cm (2008 VE Omega) Payload: good question...out of interest why do you want to know this? ie do you want total weight it can carry or total volume of cargo area in litres (being a wagon, not a ute...) (more details on different year and model at: Car Prices - Car Research - Search Car Prices & Values Online - RedBook.com.au or Holden VE Commodore Specifications
OK Take 2 I've read the question now (measurements taken at bottom of wagon) Width (at narrowest) = 116cm Depth (at left side) = 110cm (measurements take at middle / just below retractable curtain - see photo 1 for example) Width (at narrowest) = 123cm Depth (at left side) = 78cm Height = 72cm All figure are approx. and if anything 0.5-1cm smaller. Figures taken using my '09 Omega Wagon Here's some pics I grabbed of google images to try and visualise how un-rectangular it is ie the large variations in the above heights
