A retribution car is the vehicle you buy after your original car has been taken away/sold without your approval (for example: your original car was taken in a divorce settlement or was sold by a co-signer). The retribution car is a better, saucier, or somehow sassier vehicle than the original.
Bridget: My dad was an a-hole and sold my super cute 2004 carolla without my permission!
Eden: Oh my god! What did you do?
Bridget: I bought an even cuter 1987 2-door BMW in amazing condition. I paid in full so the title is in my name and sent him some pics of the new vehicle.
A noddy car is a poor looking and very cheap car, something like an old mk2 Nissan Micra or a Vauxhall Corsa B. These are generally disgusting chunks of metal on wheels, and are the type of car to be driven by the delivery driver of your local takeaway.
Ugh, just look at Olivia pulling up in that grim Corsa B, it's a right noddy car that is.
