Barracuda Formula S Experts Opinions Needed

It does have a tach and he said all the guages were sent off to be repaired and recalibrated. The motor sounded strong and the tti exhaust was nice. He preferred orange over red paint for the motor which isn't a big deal. Yes there are several minor things and I agree about having the body inspected. What do you think about the 73 dart disc brake/control arms upgrade?
