wilbur, what is the price on the classic brand? I can never find one for those. It seems that autometers will run 450+ dolphins just a shade over 200 or tpi tech for 300. The tpi ad mentions they use glass lenses, and no dip switches to calibrate the speedo, just a single button that can be anywhere you want.also in the system is a oil change reminder and speed warning if you choose to use it. How does the classic system work?
