Dude, im also 17, I don't have a car yet but y uncle owns a new infiniti Q54 and the thing is pimped out, it's got a navagation sysytem that could get you to the moon, it's got auto temp censors so it automaically turns on the heat to the right setting, it's got more luxury than the penthouse of a New york suite. It's Boss, but it is an SUV, but the coupe you have listed has all the same features on in a car. My advice to you is GET THE INFINITI. i am only 17 but a smart ass 17 year old. I've recently been restoring a 1937 ford pickup custom extended cab. I have been to many auto shows, classes, and have been studing cars since i was in diapers.
