GURPS Vehicle Builder

GURPS Vehicle Builder is the official vehicle-creation program for GURPS. Like the GURPS Character Builder before it, GURPS Vehicle Builder lets you design, optimize, store, modify, and print out vehicles of all types, from an oxcart to a space station! All the system's features are supported, with complete vehicle creation rules from GURPS Vehicles, as well as GURPS Vehicles Expansion 1 and GURPS Vehicles Expansion 2. (Source: Publisher blurb)
