Looking for new or used Hot Wheels collections - $999 (Brooklyn)

Like several others, I'm looking to expand my diecast car collection.
I'm interested in buying the whole collections if anyone is looking to sell.
I can drive on the weekends or semi local during the week day evenings after work.
I'm not really interested in a bunch loose cars unless they are older and in good condition.
I have kids so we have plenty of loose played with cars.
I'm looking for our collection into the future.
I can pay reasonably.
Just let me know if you've got a big older collection to sell.
Not looking for several collections and will delete after we get a bunch to go through.
Thanks all! Have a great day.
