The obvious trad issues with so little use. I assume rear drum brakes so the piston seals are probably shot. Tyre condition and age.
The plastic rads fail. I have one off my 2014 Roadster that I replaced but wasn't leaking when removed your friend can have foc if it helps.
The rubber boot on the rack and pinion can split.
When were the brake and clutch fluids last checked?
Go on the dvla website and check it's MOT history.
I would question why the mileage is so low.
