They do a yellow Flat Rad. Build a hood and break a windscreen . See if you can tell what's incorrect with the car.
I watched that episode a few days ago Mark. I'm not a Flat Rad expert, but it was clearly well modified. The black wheels I didn't like, and I doubt yellow was in fashion when it was new. The screen was most peculiar and clearly not as it should have been. I can't remember how the interior looked. The hood looked good when finished but I didn't like the forward cantilevered frame, which looked like it was for a different car. MGT maybe. And I don't imagine Flat Rads had mohair - maybe double duck?
