Did you notice that Edwards car in twilight is a silver Volvo, but in new mon it's black, whilst in the books it's silver??

Yes,,,It was a huge issue before New Moon came out in 2009. They gave the original one away to a fan on the Tyra show and then when it came time to film New Moon..t had to be changed as the model was no longer being made.

Actually in one of the interviews they said it was sliverly black maybe they thought it was more safer the XC60 is the safest car yet and its Volvo
