Lotus Carlton was a joint venture between Lotus, and Vaxhaull (Holden/Opel) - I think the idea was a different engine, and a series of chassis tweaks by the Lotus boys - I believe the results were seriously spectacular, although in my opinion it's still a dog ugly car.

Commonly driven by chav's, the astra boasts very little power, and generally speaking handling that resembles wobbling a spoon in porridge. This is often caused by owners who feel the need to add expensive suspension parts to the rusty bulkheads in a view to racing up and down long straight roads.
The design was copied by Daewoo a few years ago, but surprise surprise, nobody wanted to buy one....
