We try not to put our vehicles thru ****, but the replacement for our Ford Expedition will have to cope with High Water that floods several intersections on the only road home during heavy rains. We're not foolish enough to venture into flowing water, but the only danger in these placid puddles is the embarassment of being rescued and the cost of rebuilding an engine after a water induction event. The SUVs we've driven for the past 30 years have all been up to the task, and we're reluctant to compromise that capability. The Mercedes GL450 (my wife's first choice) advertises a more-than-adequate fording depth of almost two feet, and the Hummer H3 and Land Rover make similar claims. I hope none of you have found the Enclave's limits the hard way, but I would appreciate hearing from any of the Buick or GM insiders as to what the design criteria was in this area.
