brother i'll advise u to give an add in newspaper, & here @ pw as well,
C how much money u can fetch for ur car in its current condition. if its a satisfactory amount then perhaps u can sell it, if u're not getting good money then mite as well get it repaired.
another factor to consider is that get the car repaired only if u intend to keep it for a long time, otherwise u'd lose money that u put in its repairs, since u'll get all the stuff done ur self, u can get v.good work done, & ur car shud stay trouble free for quite some time.
