Thanks for all the advice mate.
I made sure they done oil and filter change. I have it booked in to have air filter, spark plugs, coolant and gear box oil changed. Also just purchased brake pads, braided lines and new fluid.
Unfortunately the car came with no service history so if and when I get any free time I am bringing it all up to scratch before I start modifying. I didn't know about the valve clearances, are there any tell tail signs that they need doing? She runs pretty quiet apart from what I think/hope is a rattly heat shield. I have a rattle coming from either the front (cabin side) or behind (engine bay) fire wall.
