There was a '73 mercedes SL there too (seen next to the Caddy). I always take a minute to look at older mercedes to check their build quality/engineering. Time & time again, as personally viewed on '50s, '60s, '70s and '80s versions, they're no better engineered or constructed than a Plymouth or Rambler. The hood springs are anchored to the inner fender sheetmetal. There's thousands of screws & panels & fasteners to bolt them together, just encouraging rattles and corrosion. The '73 was a little better than the '59 I looked at a few years ago, but not by much. Front bumper is still in 2 halves and bolted together in the center. There was a dicey welded patch at the lower corner of the grille opening, and there was no evidence the car was ever repainted that I saw.
TONS of marketing went into the illusion that it's a top-notch quality piece, but reality really shatters that myth hard. It's a plebian, plain little car loaded with cheap bits and mediocre construction.
