Do you mean who made the originals for filming? If memory serves its was Michael scheffe (also in charge of the contruction of BTTF's Delorean) who originally desgined K.I.T.T. and George Barris designed the later convertible and SPM versions. The A-Team van was supplied by GMC as can be seen in the closing credits and I would assume it was a similar deal for Chips but as with all tv vehicles, dont look too close at the stunt vehicles as K.I.T.T. has been models, had a shell over the top of the car and even and complete fibreglass version with a space frame chassis used for some turbo boost shots. Equally the The A-Team van has been a Ford Econoline on Jumps and the Chips lovely Kawasaki's have become scramble bikes for jumps and stunts.
