My classic is modified - it's a Droopsnoot Firenza, and is basically in Group One spec (minus roll cage/fire extinguisher)
But otherwise basically group one engine, my own brake mods, modern dampers and poly bushes etc
On the seats front - while i appreciate the originality of low back seats- both my parents now suffer from whiplash from two different car accidents (none of which was their fault) so since I can't help think that head restraints are a good idea. Personally I've decided to really impress the purists and got a set of bucket seats from a Subaru Impreza to go in the front of the HPF
