It's an amazingly large market, I bought some last week for my son... Not sure if they are what you're looking for. Sunday is the best day, but if it's raining that wouldn't be any good.
It depends on the day and week, different people bring different stuff, I for example found pop figures and pokemon cards some days, and few others, but I've definitely seen lots of hot wheels
Yes I have seen hor wheels for sale
I did see a couple vendors selling Hot Wheels
I can say you can look around but there is also a goodwill there too you can make a day looking around and they also have great produce
