ok dont all laugh at once.... I have the opportunity to obtain a fiat x-19 with a stash of spares, been dry stored for 4 years. The best part is its free!! Just wondered if there were any kits that used the x19 as a donor or should I stick a bike engine in it and have a cheapish laugh??? Any suggestions please...

Keep it original.
They are becoming quite collectable now.

I had one twenty odd years ago. Great fun to drive.

Yeah leave it alone. If you really want to build something, clean it up and sell it, using the proceeds as Locost funding.
