When we were deciding on the 6cyl or 4-banger and were test driving, It was important that I was happy with the start-stop functionality. Unfortunately, by the time the engine was at full temp and the battery was charged, there wasn't enough fuel for the feature to work. The dealer we work with put enough fuel in for us to test it out even though we had no intention of getting that KL (We wanted to order). I thought this was nice. They also put a fair amount of effort into finding us money in spite of the fact I already supplier discount. They ended up knocking another 4k off of my supplier price. When we took delivery they did not fill the tank, but I'm not complaining. They made and make up for this in other ways. I tend to complain a lot about dealers and their techs, but ours really hasn't done anything to deserve it. The parts guys are about as sharp as boiled onions, but nice and work hard. They also work magic for me on part pricing.
