I'd guess this one is Porsche powered ;-)
Fox, it's not only Porsche powered, it's a legitimate Porsche, a 1956 Porsche 1600 Beutler Coupe
below is the engine they came with, this one in a beige coupe
look at all that room, and the engine access in that engine compartment, love it!
Here are some more images of the red coupe
I just did a little more snooping and found they made a cabriolet as well
I want one! (dream big)...
This blue cabriolet was once owned by Grace Slick of Jefferson Airplane fame
(I'm pretty sure I will never be able to afford one)
