I can't choose from vehicles?

I have a 2002 ford expedition xlt i'm 18 and getting ready to start college i love SUV'S so i've been looking at a used 2013 ford explorer limited and a used 2014 Acura MDX i love both vehicles. I have more then haflf for explorer but not acura i want to build credit also and i have a trade in what should i do? I really like the acura but it's luxury and insurance would be wicked.

Added (1). and which one would last the longest after i'm doing paying it off.

Eeny, meeny, miney, moe.
