I don't know the deal with those cars but I'd take the one w/ just the rear wheels missing. I know Ford doesn't destroy all the test cars cause I have one. I got a 94 gt that had a 4.6 in it. My friend had a good connection at Ford and they gave him 3 cars because he was the A/sedan champion 2 years in a row. 2 of them were test cars and the third was a body in white. he had to give up racing cause he got lyme disease so I got one car from him. Its has 173 miles on it! I wonder what they can tell from testing a car in 173 miles. It also has some funky alum. spacers inbetween the frame and k-frame I guess to fit the mod. oh and also has the hydro boost which I don't think they had in '94. also had hundreds of extra feet of wires I'm guessing for test equipment.
