I'm surprised that a higher value, substantially higher power, modified car was cheaper to insure. When I was shopping for insurance for our Leon Cupra R Abt around 3 years ago, I got some cheaper comparison site quotes, but only because they didn't know exactly what the ABT uprate was. As it happens the Leon did get an ABI classification, so it is recognised as a separate model for insurance purposes. Changing the subject I wonder if the Formentor ABT only gives the 370 bhp in ideal conditions.
