Need help id'ing Die-cast cars on auction

[trekfan]

Hey guys, I won this auction and need info on the cars.

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=120119038630

The ones with cases (and license plates) are marked: 1983 Hot Wheels.
The Mixer and Rescue Vehicle are marked: 1979 Hot Wheels.
The Green, with black and white stripes, race car is marked: Marx.
The Silver Dragster is marked: Lintoy (made in Hong Kong).

Any info would be appreciated - I only bought the lot for the Spidey Car and am planning on selling these. Thanks...

David
