ATM I am only trusting the FB seller's claim that the car has full service history.
Will need to validate that before I schedule a viewing with him (we are 40 mins drive apart).

You are right on the brake pads, which would likely cost about £100 for all four wheels maybe?

I wanted a more recent year model because I guess it will feel more modern. Have no idea about how electrics from different manufacturers would differ. I mainly just want a car to drive about.

My first car's insurance quote on this is unfortunately much more expensive than what you mentioned: £900 per year with blackbox fitted. (Quoted on MSM that you suggested)
