Hey, now -- that was my first car!
I had a '75 4-door, the slightly upscale model. No vinyl roof or exterior vinyl trim, but the interior was better finished than the entry-level model, with a little chrome here and there. The engine in mine was the 250 c.i. six-cylinder. My car was a metallic lime green, inside and out. (Well, the fabric facings on the seats weren't metallic.) I always thought it looked much like a 4-door Mustang.
It was reliable, the A/C was good, and wow, how much I learned about maintenance on it! I could change my oil, coolant, filters, inline fuel filter (it screwed into the carburetor!). And I was so glad to have a car, any car, after years of trudging between bus stops and begging rides from friends.
As for the point of it, it was a good first car, good basic transportation, like today's Cobalt or Focus, or a Corolla or Hyundai.
