Good lad
Good haggling point - one which I should've used

- is to check if the IMRC is working. A new one from Ford is £140.
This is the Inlet Manifold Runner Control that opens up the secondary inlets at approx. 3500 RPM. Take it for a drive, wait till warm, and hit about 30mph in 2nd (revs should be about 3000 RPM). Floor it. There should be a nice grin on your face as the secondaries open up and that rev counter needle flies round toward the redline.
If it's not working, you may find the car struggling to get over 5000 RPM.
If you knew this already, then I hope I served as a reminder
Hope it's as nice as it looks!
