I bought a 1997 R-plate 2.0l 10valve petrol v70 this week: £1995 with 128k, fully serviced up to 114K, which runs well and seems like a lot of car for the money etc....but, the driver door lock is not working in conjunction with the rest of of the central locking, and needs keying open separately, tho all doors lock together with fob..this also confuses interior lighting which sometimes comes on/off with the locking, or refuses to go off, so Im keeping it off to avoid accidentally running the battery down...seems quite trivial, I know, but it's irritating.!Any ideas? Otherwise a beauty - is 25mpg about right? Thanks
