hi. i'm looking to buy a frontier this summer since my 240sx is getting kinda old in the snow. i was looking for a 4x4 supercharged kingcab model (i'm also looking at the supercharged xterra but the frontier is more my style). my question is: whats the hp of the supercharged (vg33re?) model vs the 3.3 v6 model (vg33de or vg33e?)? are there anything i should look/listen for when i start out to test drives?thanks for your help
