They probably look great in 19s, though if one has damage and curb rash, I'd offer less than $800. That fourth rim is basically no good, it can't be repaired without being re-chromed, and thats the cost of another wheel.
What size tires are on two of the wheels? Also btw, you WILL HAVE TO roll you fenders to fit those wheels, with that offset adequately, especially so if you are lowered at all.
Btw, I love the color of your (and mine) Titanium Pearl Galant 8)
