There was a smaller model of the Star Speeder 3000 made several years ago and sold at Disney parks. Depending on how one fudges their scales, it could either be between 1:48 and 1:64 scale. It had the droid pilot figure, R2D2, a full cabin with seats, opening doors, and well-integrated lights and sound. I never got one myself, but my younger brother did. I do have some of the Star Tours droids on the POTF2 cards, however.
As for the ride, if you have not been on it, fork over the cash and go to Disneyland (or Disneyworld). The ride is totally worth it. While the time has come for a makeover, I still really love the "Original Trilogy" feel of the existing ride at the Disneyland Park in California. It does an excellent job of making you feel like you've entered the Star Wars Universe, even if the events are a little non-cannon. Having grown up with the original films, Star Tours was such an awesome experience when I firs rode it as a kid in the late 1980s. I got to do all the Star Wars things I wanted to do: go to lightspeed, fly through an asteroid field, shoot TIE fighters in a space battle, and fly the Death Star trench run. Too bad all kids know these days are the prequals and the Clone Wars cartoons... They're just not the same.
