I've had a 2000-ish interstate logo Route 66, in blonde with matching Z-Best, for over ten years now. It was an amp I pined for and saved up for and bought (used). Still love it. My early Mesa Marks work a little better for the main project I'm doing now, but man that Route 66 is sweet. I will never get rid of it. That amp, more than any other, has led to more "tone" compliments from non-musicians than every other amp I have combined.
