A sort of 'what car' - Need a shed... fast! (London/SE)

[veevee]

I bought my Golf while my 306 was off the road, now that doesn't work either! Pain in the arse. I need a stop gap car fairly quickly. Right now I'm not too fussed what, I'd like a 205, but there don't seem to be many about!

Requirements:

~£500
Reliable
MOT
Pref with tax
Economical
Easy to sell on when I'm done with it, no v6s, etc please!

I can already guess the cars which fit the bill, just need to be pointed in the direction of actual cars for sale.

Thanks!
