Lets do some background on her in the movie. She knows cars ( except for the editing mistake that gave BB a sweet engine when they popped the hood, that shot was added later) But in the movie shes supposed to know cars...alot more than Sam..and probably knows cars and expects more..so to her it is a peice of crap..and truthfully he was a POS..the paint the bodywork the stinkbeetle stance. Something one of the HS Elite jock/preppy/popular would not want to be caught in..Fox was that in the movie...Sam was not the popular kid..heck she did not even know him...
And she had a point. this advanced alien robot that can transform into anything they need to hide and blend in transforms into that Camaro??
Jazz knew what he wanted, Iron Hide and Ratchet..even Prime..
Taking a line From Hot Rod in the first movie:
"If your gonna ride Danno..Ride in Style!!"
now if your 67 and your 98 are nice cars and she said that then yes thats shallow..but an honest observation to the owner of this robot..and she got her answer..he changed into something that really boosted Sams "gonna get some" points.something with style .a 5th gen Camaro.
and something tells me if you had a gf like Megan Fox I really dont think you would be kicking her out of the car for an honest observation if your 76 was really a POS that turned into an autobot..the situation and the dialouge fit the movie and the scenes perfectly..and if it was not for her..then we would not see the 5thgen in the movie...
