I love my '03 SL/2wd though wish the rear springs/axle was a little tougher. 4 people (230 - 250lbs ea.) in it it puts it near its limit and lets it bottom out a lot. Anyone have thoughts on an airbag system or something? Also I find it doesn't like railroad crossings and it sounds like it's crashing against the stops in the rear even when empty, as I go over them.
