my little A210 has rust around the rear arches, a quick blast of bright zinc galve spray every couple of months covers it up nicely as its exactly the same shade of silver.
I thrash it every time I take it out and its not let me down in 2 years yet!
theres one exactly the same as mine with the same colour wheels as well with no rust for £950....its such a fun car I might just buy another one for when ther mot runs out on mine ! it would be cheaper than getting the rust and niggles fixed!
