This dilema *****. People say ebay is always wrong when they say stuff cant fit in their car. anyone know a website that this can be proven thick and thin?
what car do you have that doesn't allow most HU's to not fit? are you looking for some type of double din HU?
after you get the size that is accepted into your aftermarket harness(if necessary) just look around at other sites. heck i'm sure you can find a better bargain for an HU at an other site rather than crutchfield
There should be no problem putting a premier or any other deck in the cavalier. The only problem you run into is that the harness is expensive and you will most likely have to stash the factory head unit in the trunk.
