muko Do your homework carefully. During this period of FORD darkness there were some oddball transmissions that were rubbish and possibly engines that are best avoided.
Watch out for FWD only, early VEA engine (or non-volvo engine) and powershft transmissions. Google ford powershift.
Earlier VEA engines had high oil consumption issues especially if oil changes were stretched. This was not "fixed" until 2017'ish.
If it doesn't have 5 cylinders or a reputable indipendent volvo specialist history you can check out directly with the mechanic I'd steer clear.
