best cheap car i was thinking 500 quid peugeot 106 with nice miles or a clio, with a nice healthy budget of 3 and a half g's i would get a yaris diesel if she's doing miles.
them cars are fantasticly reliable and they do sell well even with big miles after you have finished with them,at least try one. verry nippy and don't go wrong,look on autotrader or ebay and theres 6 year old examples for still more than half what they cost
