Today I was climbing up from the Queensferry Crossing towards the A92 slip when a Crosstar overtook me. Immediately behind the Crosstar was a Mk1 Jazz. As the Crosstar returned to lane 1 the Jazz overtook the Crosstar and the two of them were side by side for a few seconds. The Mk 1 looked the taller of the two. Now I have checked the dimensions and the Crosstar is slightly taller (31mm) but whether it was the Jazz roof is higher than the Crosstar's or because the Jazz being a little narrower made it look taller, or maybe just the camber of the road but the Mk1 definitely looked the taller of the two.
