In my experience, most mechanics will try to convince you that aftermarket parts are a waste if they are not an enthusiast themselves. They are so used to seeing cobbled up stuff that they usually push people away from aftermarket parts. I wouldn't give the guy to much credit because he obviously doesn;t know much about the 370. You've made a good choice and will be very happy with the money that you spent.
