I can anyone give me an idea how much a 1995 850se 2.5l 7 seater
estate might be worth.

It is in very good condition but has high milage (188,000). It has a
full vovlo service history up to 120,000miles. It has 6 months MOT and
tax.

I'm thinking of buying one and don't want to be ripped off.

I would also appreciate any comments on the general reliability of
these cars etc.

Many Thanks

Doug
