That's a little scuffy but not all that expensive. $400-ish seems to be the sweet spot for late 80's mid-line bikes right now in bike-friendly cities.
Tektro levers, new-ish wheelset & saddle are reasonable improvements regardless of your size or riding style. The stem and bars are different but not what I would consider an improvement.
I paid a little more than that last weekend for a MV version that was a low mileage original basement queen for a future build project and about the same price for an '85 with 600.
