I have never had a car with cruise control before, and since I don't drive standard I don't drive my husband's Jetta that does have cc. I think my cruise control works fine, but I only use it on relatively flat areas of the highway. My husband, on the other hand, says that his Jetta's cruise control keeps the car at EXACTLY the speed he sets it to, and he thinks the TCH cruise control is wonky because it varies up and down by 5mph.
