Essential Pre-Purchase Step

Buying a used Subaru Outback Mk2 (BH)? Always check for hidden finance and write-off history.

Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.

Inspection Checklist for Subaru Outback Mk2 (BH) Buyers

If looking at a 2.5L, assume the head gaskets will need doing by 100,000 miles if there is no record of replacement.
Check for "torque bind" by making tight circles in a car park; a hopping sensation indicates AWD center differential issues.
The 3.0L H6 (H6-3.0) is much more reliable regarding head gaskets but significantly thirstier.
