I only had the 1:36 Corgi and 1:64 Corgi Junior toys as a kid. I know there was a 1:18 toy of the Lotus in car mode more recently, like a few years ago. It looks like there was a 1:18 submarine version too.
I have a 1:18 scale version made by AutoArt.
It has fins that swivel, doors, hood and trunk open, and the propellor veins swivel. Also has a torpedo launcher on the front that opens as well.
I could have sworn I saw another 1:18 model that allowed you to remove the wheels and convert it into the sub mod....Can't remember who made it though.

Jet - 1:64 is Hot Wheels size. the 1:18 car is 9.25" long and should be in scale with the other hollywood cards you're talking about (Batmobile, General Lee, Mach 5, etc.). I did a quick search and it looks like ERTL/Joyride made one with the parts to convert form car to sub mode.
I always wanted a 1:1 version of the alarm system that car had in For Your Eyes Only.....try and steal the car and it blows up. Now THAT's a crime deterrent
