I am sorry, but I have *NEVER* liked kit cars...and I mean "NEVER*....the knock off Porsche 911, Ferrari and Lamborghini ones are *simply* the worst.
The build quality is crappy as they are mostly fiberglass from badly made moulds, terrible noise and heat suppression, uncomfortable interiors, the wiring in my old Console TV is better, they all run bastard engines (in your case an old roachy carb'd 10A, 12A rotary - no thanks!), tranny combos...they have one plus and only one..they are light...but would you want to get into an accident in one?
You are selling two great sports cars that demonstrate build quality, performance, handling, safe, reliability, good looks...I could go on and on...
The novelty of driving one of those would wear off faster than a Sunday morning hangover.
Sorry for being "hard and cynical"..but you asked.
