Well we don’t see any monetary transactions, but:
[spoil]After Lightning’s
trial for ripping up the road, Mater, who acted as his “lawyer”, says Lightning owes him $32,000 in
legal fees.[/spoil][/spoil]
I
still couldn’t see Lightening or any cars pay actual dollars. It’s like seeing Marlin paying Crush with a
dollar bill for the ride on his shell…
Hmm, yeah…They might have
named their currency ‘dollars’, but I don’t think they actually used cash. Then again, a lot of the things in
the Cars world don’t really make sense. How could they build things with only tyres as ‘hands’, for
example?
Ohhh…I’m sure they have ways. The Pixar team seemed to make
their cars’ tires more flexible, so that they can move stuff around more easily. Unless they have psycic powers,
I suppose they could use…umm…well…I dunno. 
If they have more characters like Mater then it’s quite self explanatory…
I
remembered playing a game where you gotta collect lug nuts & use it to purchase/unlock stuff…now I’m fully
convinced their currency are in $ form but as in nuts instead of bills…
But, do CARS eat like food or do they just drink gas? I
mean ice cream do they call it cars cream? 
I need to know give me some answers
I’ve sort of thought of currency in the Cars world as
not being tangible at all. In our world, we’ve got credit cards and bank accounts and all that good stuff, and
cold hard cash has seriously fallen more and more to the wayside… So, I haven’t think on it a whole lot, but
my thoughts were that money in the Cars world is just the sort of whole non-tactile, “digital” credit
sort of stuff.
I have another thought but it won’t work (you see why after reading my idea) They get credit & instead of
cash for doing their jobs. To pay off goods they use their form of credit card via car license plate & scan
through. The problem? Not sure that every car in the film actually have a license plate…
Hmm, that is a nice idea,
though I know what you mean about not all cars having licence plates…Really, in Cars, Pixar didn’t completely
reveal everything about their world, so it looks like they want to keep us guessing.
As I
recall seeing the many trailers I think there’s only 1 (or the same kind) car that has a license plate;
Fred
Where do baby Cars come from?
I have thought the same thing.
if you go on the web site and do the 360 view many of them have liscence plates

when a mommy car and a daddy car love eachother VERY MUCH
…
…
… they go to the dealership !!!
this gurl in my class was like "where do they come from
"
i laughed and told her that
I have an idea…But I’m not sure of the age
group of the forum yet so I’ll keep it to myself.
I
guess I always thought they would just build them.
Here’s a better
question, if they have kid cars, they’re much smaller than the adult cars right? What type of car is small
enough to represent a child?
Peddle Cars? Or pow pow Power Wheels!
Thing is, if they had kid cars, would these cars ever
grow?
I have that figured out (I just need
to figure out what type of car that can represent a child) Anyway, to symbolise that the kid has grown up they
get an upgrade
