"Theirs" is to be used here.
But you can use both of the following:

The car of theirs is just amazing!
Their car is just amazing!

    Just to note: the latter is way more natural to say.

    What about That car of theirs is just amazing? Wouldn't that sound better in the first example?

  • @Smock Not necessarily. Only if you're pointing out to a car.

    @BellaSwan or just referencing someone's car in conversation (at least in BrE). [talking about the Robertsons] That car of theirs is just amazing sounds much more natural to me (lacking any context in the OP to the contrary)

  • I believe we use "that" when the thing(here car) has previously been talked about! Jul 11, 2019 at 13:12

Their is subject, them is object. You would mostly use 'them' at the end of a sentence i.e. something is done to them, or I took the car belonging to them. The word 'Their' always precedes something which belongs to 'them'. i.e. Their Car their holiday etc. I hope this makes it a little clearer.
