I f at all unsure about your ability to check a car for faults, pay the AA or RAC or someone like these Pre-Purchase Inspection - Next Car Check | Used Car ChecksIm honestly useless with tools. I have a friend that has a workshop and he usually carries out my maintenance and repairs on my cars for beer tokens, plus parts at trade prices help the wallet.
Plenty around just google car mechanical check.
I had a s5 v8 that was too far away, the mechanic rang and told me not to bother still sent a report, the seller tried to get a copy and haggle the price, I told him to pay me for the report..
Well woth the price
