I know that today Corgi Toys & Mattel Hot Wheels are making some really great diecast cars of Batman but about 14 years ago a company called Ertl was making some really wonderful diecast vehicles for Batman : The Animated Series. They did the beautiful Art Deco style Batmobile from that now Classic Cartoon. They also did a Gotham City Police Helicopter, The Bat-Jet, Bruce Wayne's Car, The Bat-Boat/Submarine, & even the Bat-Bike! They were really nice quality & look great too. You can find these vehicles today on eBay pretty easily, here's a photo of all SIX in the set.
