I've stirred up a few strong opinions!
Replicas can take many forms, from the body kits covering a different donor to mimic an original, to the bespoke body/chassis re-creations of vintage classics.
There are some superb 'D' type Jaguars and the like out there fastidiously created from scratch.
Firms will even cast you engines and cylinder heads from original drawings.
The Stratos kits stop short of re-creating the steel centre tub. I wonder how much that would cost? Uneconomic for the UK market I am sure.
I still think a set of Stratos panels could be grafted onto a Fiat X1/9....
