Based on photos and screengrabs cockpit looks right to me. Those little red buttons look translucent too, it would be cool if they lit up with tiny LEDs, but not a deal breaker at all. The gauges look fine as they are though. They weren't backlit at all in Batman or Batman Returns. The Batmobile cockpit reminds me of the instrument cluster of a WWII dogfighter.
Other things I notice from those shots, the side pipes seem to be molded onto that flat metal piece or at least glued to it. It doesn't look right to me, but the detail on the pipes is impressive. It even looks like there is some heat damage to them!
The front tire treads look too big and in the wrong pattern. This is not something you can easily see in the movies, so I don't think it will be a big deal to most collectors, it's just something I noticed from photos of the car. I can't see the rear threads closely enough to say if they are accurate or not. Again, not a big deal, but it is wrong. They can get the threads right (or very close) with the Tumbler and Batpod, they can do it here. Call the nitpick police!
Also, one of the specks of dust on the left gun cover is 0.00000045675 millimeters too close to the edge and rotated 0.000056243 degrees southeast of from how it appeared in the scene where he destroyed the factory.
