Yes that's correct. Caterham took over the manufacture of the lotus 7. The lotus 7 was Colin Chapman taking an Austin 7, a British car from the 1950s and removing the body and other parts to lighten it, as he called it "adding lightness". If you Google Austin 7 chassis you will be shocked how flimsy it is, your bed frame is probably more rigid, but that's the 50s for you.
The Caterham has been much developed over time, although it does not have massive v12 engine, it handles superbly so will leave super cars and indeed motorcycles behind on a racetrack with short straights.
To my best knowledge the GL reverse is by means of starter motor.
