Replying to Bummed out though i dont think i should be

ok so im 16, 17 in about a week
ever since i got my license ive been driving one of my fathers cars, and audi a6.....needless to say i was hella thankful for it and pumped to drive such a nice car.....
i was only driving it till i got my vehicle, which my dad says was gonna be a truck, preferably a f-150
he came home at least twice a week with pages printed of websites of trucks he said he wanted to get for me, most of them were like 2004 f-150's and 05 tundras.....
today he came home with my vehicle, a 97 camry.......
i want to be like thanks dad for buying me a car, since i know im really lucky to have parents who will buy me a car....but hes been telling me hes gonna get a really nice truck for like 4 months......so im like agry/depressed/pissed off.....
do i have any justification for my anger?>
