DS2: On-line vehicle generator beta testers

The new version of my vehicle generator is up and running. This version
includes a lot of error checking. The last version didn't,
and as a consequence, maybe 1/3 or so of the vehicles in the showcase
are illegal. <:) If you'd like to bang on the new version some, let me know.
I'm looking for people who know DS2 vehicle generation pretty well and can
help me find subtle errors, but anyone is welcome to look for the big ones.
