When running properly they are a joy to own and drive. Having owned two Interceptors, one FF, and two Jensen Healey's I also know the dread of owning these cars when things start to act up. They have temperamental English wiring and fuzes (Lucas, the Prince of Darkness...) along with, in the Intereceptors and FF, large engines packed into tight/very hot spaces. Still, I love owning rare cars that you won't see passing you on a typical drive.
Its a great documentary but i see alot of faulty information. For example 19:14 Jensen didnt produce the first fiber glass vehicle and it wasnt the first to have seatbelts as standart
