What will it cost you to change?? A lot more than fixing this one!
If you can do all the work yourself it's a no brainer- keep the car. Even if you've never considered picking up a spanner, then now's the time.Get the pipe done at kwik fit or somewhere, buy a Haynes manual and do the brakes yourself- not difficult at all, even for a beginner: basically a nut'n'bolt follow the manual job.
If you manage that then wheel bearings are within your scope, and if you havn't got any welding gear, get it done by a mobile welder at your house.
Even if you can't do ANY of it, you'll still probably have change out of 5 or 6 hundred quid, and then you'll have a known quantity car for the next year, and what sort of other unknown car will you get for that??
Keep it!....says someone running a 17 year old quarter million mile Citroen BX as a daily drive......
