This is my dad's 1969 sunbeam rapier fastback he built from scratch.
It has a Lexus 1uz 4l worked v8 with a 5speed manual gearbox. Pretty much the shell and front windscreen is all that's rapier still. Just under 1000kg with over 500hp. Full roll cage etc and the best thing about it is it's road legal.
Amazing unique one of a kind car.
I reacon around 100k over 4 years build time.
He also has 3 more fastbacks
