Spare parts to have available for d24

[Impolvo]

I'm picking up 2 d24 m46 262Cs soon
There is a great hoard of spares available anything I should pick up to go with the cars or look for?
Sorry if it's a dumb question
I've had a whole pile of volvos from b21,b23 ,b28,b280 b230 b6304
But these are my first d24 cars
Both were running in the last 2 years when parked
Anything I should check out before attempting to force them to life
