To me previews are good for someone who wants to see some detailed specs, price and the front/rear views, without drilling down the manufacturer websites. Some manufacturer websites are not well organized imo, in some cases they seem to make difficult on purpose, to force the readers to spend more time there.
Measurements take time for sure, but if you are not too far from GTA/Canada, now that I am sort of retired, I would love to do measurements for you but I don't have an AP and shipping costs may be too much for you.
