Is the 850 GLT a good car. l am planning on buying one which has done 85000 miles and has full service history.It is a UK car and would appreciate estimates in £'s.

l would not give more than £1000 with it being only a glt model as long as its been looked after and serviced it will outlast a modern car all volvo is tend to eat front tyres and drop links check for any oil leaks.Start the car and let it get to operating temp then remove the dipstick if there is puff is of smoke coming out u need to either clean the pcv system or replace it

if records do not show a timing belt,have it done immediately.
replace all related components to include timing belt, tension wheel, idler wheel, gas grenade, and water pump and any seals that have started weeping [generally these are still dry at even 300k miles]
with the pound worth approx twice the us dollar l would expect to pay up to 2000 for the right car.
average on these in the us go between 3k and 4k for low mile cars in top shape
