The paint looks really great if you have poor vision. My car looks immaculate with my glasses off.
I just sold my (also red) 1991 E36 318IS. The 318 had about 200k more miles, with less rock chips. This includes several pairs of 200tw tires and winter driving.
The FRS doors/side skirts do not handle rocks from sticky tires at all. Ceramic coating probably works wonder, I'm just too cheap to spend a 1/4 of my car's value on protecting the paint.
