Ah nah nah :-) You could use 'there' as both a presentatoinal and an existential word.
a) Presentational
If you'd like to use 'there' to refer to something which is not close to you usually use a subject after emphatic 'there' i.e. it's stressed.
'There you could find some cars.'
(However I associate it more to there as an adverb here)
or you could use it in the fixed phrase 'There is/are...' in which 'there' carries the stress again.
b) Existential
Using 'there is/are' as an existential phrase doesn't have anything to do with the distance. Actually you could drop 'there is/are' and rephrase the statement without a change in meaning. Compare:
'There is a pen in my hand.'
could be changed into
'A pen is in my hand.'
I don't know about you but I keep my hands pretty close to me. lol
To compare what I said about 'there is/are' with 'here is/are' see the link below.

BTW 'Are here any cars?' sounds awful! 'Are there any cars here?' sounds much better. You guess why based on what you see above ;-)
