Got a little story for you guys.
I was just leaving work last night at 6:00pm and I get a text from my brother. It says "you still got them tow straps in your bimmer? I got my jeep stuck in the snow, so embarassing" I ask him where he is, he got his brand new 2011 jeep grand cherokee stuck in a snow bank behind his work while testing out his 4wd system. I drive over to his work, and there he is, stuck in a foot of ice and snow, truck is high centered and all 4 wheels are sitting on ice now. I get out, hook up my tow strap to his truck and start pulling. Engine stalls, start it back and pull again, engine stalls again.... too much stuck weight to dead pull. So we give it another go, this time a little lighter on the clutch (dont want to burn up my clutch either) after about 30 seconds his truck is pulled up and out of the 4 big holes his tires made in the snow. We unhook the tow straps and I drive my car into the snow bank and right back out again.
So moral of the story, e30 awd > 2011 Jeep grand cherokee....
Anyone who doubts the e30s towing, his truck weighs 4,850 lbs, nearly 2,000 more than my car does. And I was able to pull him out of snow that high centered his truck with a ground clearance of 11.1 inches.
