Based only on opinion, yellow has to be my absolute favorite color on a second gen Firebird, or Camaro for that matter. I've always loved it because it's sporty and flashy. But as you have said, the color goes two ways. Either you love it, or hate it! If the existing finish is in good condition, it can be easily repainted with a scuff and shoot...using a sealer, of course. The jams would be a little extra work, but it wouldn't be all that bad. If the car is as solid as it looks, I would go for it. The 4 speed is an added bonus! I'd say it's a very good deal. But it's completely up to you to make that decision.
