Wow, did you get to ride in it? I love that car, and also that song and many other Beach Boy tunes.
I was a year younger the cooch (preferred over time because he got tired of being referred to as a 'chili dipper') but we were pretty much neighbors with about 10 houses in between us. I also spent a lot of time with him at Alexander Brothers when the car was being built.
Back then, the Silver Saphire was one bad hombre!!
