Is there an easy way to know the length of a bus vehicle that is produced in multiple different lengths without having to compare photos of different lengths? Some buses (eg Optare Excel, Optare Metrocity, Optare Solo, Optare Tempo, Optare Versa etc) have the length in their model code so you can just simply go on to www.buslistsontheweb.co.uk and type in the reg number and find out the length quickly and easily. However many other buses don't. For example the Enviro 200 was built in five lengths (8.8m, 9.3m, 10.2m, 10.8m, 11.3m) but there doesn't appear to be any way to find out the length. So how does one find out the length of an Enviro 200 bus without having to compare lots of photos of the different lengths? Is it possible to find out easily? Is there anything in the chassis number or body number of bus vehicles that tells you the length of a vehicle? Many thanks for any information.
