How long before it becomes retro?
In todays world of political correctness, there is no such thing as an old car or a banger or a nail or even bangernomics. You've either got a normal car, or if its a bit shonky, then it immediatly becomes retro, a 'project' or a 'runaround'. Not runaround is the best - even if its your only car and you dont have an Elise in the garage you can still use the term 'runaround' even though it sees exactly the same use as next doors 1 year old Focus, becuase hey, runaround is more palatable than saying 'My car sucks'.
