You should be able to find a helmet in plain black or white for about 100 bucks at a local motor cycle shop. Put a few vinyl stickers on a plain helmet and to me that looks much better than graphic helmets anyway. Especially for an auto helmet. 2000 is just a production year reference so any new M or SA Helmet will do. If a shop has old ones in stock make sure it is 2000 or above.
Cycle Gear which has many stores throughout CA and has a store locator on their website has HJC Plain Black Helmets call the nearest store once you have chosen a few different models to see what they have in store.
