I learned on my now brother-in-law's old Jeep TJ. I also learned in the snow which helped me get down the basic. I don't think it really matters what you learn on because every at is different (friction point, etc). Learning in the snow made it a lot easier actually because if you drop the clutch too early you won't stall, or stall as much I should say, you'll just spin the tires.
But, what Bout learning on one of those old jeeps? Sure they're not the most fun cars to drive, but you could pick them up for super cheap, and they're fairly reliable as well, iirc.
