I have used the Show Chrome model for over 3 years. Easy oil changes with the front section removed. It has a few scrapes and scratches. Mildly hit a few speed bumps. No Dents.... I bought the silver one for $49. and spray painted it black with outdoor grill paint. As far as the amount of holes in the pan... it is a water cooled engine, not air cooled. I am sure that all brands of this basic design work well.
