This Firebird is NOT the test 455ho Firebird the seller states it might be. I busted him on this yesterday and he has not updated his auction that it is not, so not to decieve any potential buyer. The test car was in the Fabulous Firebird book, Car Craft Jan88 and High Performance Pontiac Apr86. Although all the pictures are in black&white, it clearly shows the actual test car as having a light colored interior, probably parchment, also it has a front fender antenna, blacked out front grilles and no wheelwell moldings plus a 69 Trans Am rear spoiler.
The auction car has a black interior, power rear antenna, standard painted grilles, wheelwell moldings, no rear spoiler and not even holes in the trunk lid where a spoiler might have been.
The best clincher is that the HPP article states the actual test car is Engineering number 9723 which is different from the Engineering number 9749 on the auction cars PHS.
