First car is kind of an abomination with those headlight assemblies being a foot away from the actual car. Not to mention, that steering wheel looks retarded.
these are both definitely variants on the Caterham chassis. the first car looks literally like the book chassis with fancy fiberglass bodywork applied over the top. There are build plans available for free all over the net…even for frames designed wider to accept V8’s…sounds like the borrowed free engineering and just paid someone to make the body look cool.
