Totalheadturners was a kit car company making replica body kits to fit on donor cars, often MX5s. They did some Ferrari kits and I think Ferrari took them on over badging being sold with the kits. Similar to Morgan now protecting their logo and badging. There are many kit car companies doing Cobra kits. Remember the “is born” series on tv?
Basic Cobra with a Sierra donor car. You could keep the 2l Ford engine(

) fit a Rover V8, or a Chevvy V8. A couple of companies still offer some good versions.
Have a look here for looky-likey kits.
