Matthew,
Nice one - I've always liked the Mk ll.
I'm in the process of turning my Tamiya Jaguar Mk ll into a Daimler 250V8 - the same bodyshell, but with a different engine, a 2.5 litre V8, made by Daimler/Jaguar using the same components but on a different assembly line.
I'm almost done with the Borg-Warner 65 transmission and have the block and the heads roughed out, as well as pressed steel wheels (not the wires) and the scalloped grill ready for final tweaking to make molds and cast copies.
I have the ultimate reference - a real one in my father-in-law's garage. His is a 1966 250V8.
It's a typical Tamiya kit - extremely easy to build and easy to make look good.
Cheers,
LeeTree
