kind of having the same issue over a patriot.
not sure about on the compass, but on the patriot, they offer a 2.4 as an option on either 4x2 and standard on 4x4.
just checked.... looks like they do offer that same option for $300 bucks.
I'm trying to decide if I want to spend the extra for the psydo-4x4 or live with 4x2... one thing is for sure, it will have the larger engine. It doesn't appear to have that much more power (at least in the specs), but I've never said, gee... I wish I had less power. I'm also going for the 5 spd. I like to row the gears and so does my wife.
If I can get my Jeep Wrangler sold and possibly my Ford Fusion out right, then I'll definitely go with the 4x4.. If I end up trading the car in, then I may have to go with the 4x2... that way, I can avoid the dreaded car payment.
