Hagerty describes Condition 3 by stating that such cars "drive and run well, but might have some incorrect parts. These cars are not used for daily transportation but are ready for a long tour without excuses, and the casual passerby will not find any visual flaws. "Good" is the one word description of a #3 car." I think that's a fair description of the Boise car, based on the (albeit limited) information available in the CL ad. Let's not assume that this was a concours car a few years ago, which would preclude it from being classified as #2, but I can't see any visual flaws in the photos - if that holds true upon closer inspection (and it's ready for a long trip, man) then it wouldn't be fair to call it a #4 car, so #3 it is for the sake of this posting.
This one seems to be a great find - claimed two owners since new, maybe original paint in that nice Malaga maroon, and what looks like a very tidy interior with air conditioning and enough fuzzy covers over all available surfaces to sufficiently protect the fragile '70s plastics. What lies beneath the dash mat, steering wheel cover, and sheepskins? If it were my money, after verifying that this car runs as good as it looks, I'd swap the automatic for a 5-spd from an E21, lower the car a bit on some Alpina style wheels, and convert the bumpers to the late-Euro or pre-73 US skinny chrome spec. Here are some decent writeups on the process - doesn't look too bad and makes a HUGE difference aesthetically to the feel of the car. Keep the original parts in the garage, buff the paint, drive, and enjoy.
