Hi,
As long as the HB works then I would not worry about it too much, it is not difficult to the change the cable / adjust if needed.
Biggest concern on the D2 that is easy to check and verify is the chassis, rear third is very prone to rotting away, but do check all of it.
Then general car checks, especially for headgasket, coolant issues. Starting problems from Cold and also when hot.
As per the list check the lights on start up, it is not unknown for some naughty peeps to cover up warning bulbs .
Cheers
