I always thought it odd that the dealership has salespeople all over the place and they start out worrying the whatever out of you until you actually need one and then you go and find several just sitting around or on the internet looking for jobs. I never had a salesperson able to know all the question's I may have had but then comes the service manager who I find out from the service tech who actually answered the question that the service manager was just a promoted salesman. So I guess what I am saying is keep looking and asking till you find the CORRECT answer. Most of the time I have found that the person who knows has no problem answering or helping you with any concerns you may have. Then again some dealers you just have to look and not waste your time asking anything. Larry
