So it seems I was a bit too trusting with this purchase......
Trip to Autolusso has revealed what the previous seller was hiding.
Oil leak is more than just seals, and will be an engine out job to investigate and hopefully fix. Possible crank issues. Car didn't have oil change at last service despite being told it did.
Also non-working CD changer and car doesn't have a Nav drive in the boot.
New bushes front of rear is less of a surprise and something I was prepared for.
All things I should have checked but took on trust at the time.
Explains why last owner had it for a few months only.
Car is worth saving though as lots of money spent by the person who owned it before him.
It's going to be a big bill though.
Suggest you avoid buying a car privately from Jon Harris of Hemel Hempstead.
