There are pointers to a lot of good info in this thread:
For All New Members/Owners.
Basically, just keep up with the maintenance schedule—oil changes, cleaning the air filter, having your valves checked. At some point (6K miles or so), you'll have to replace the variator rollers and belt.
Check your engine oil level regularly. Keep your tires properly inflated and keep an eye on the tread. They'll probably last around 3K miles, but don't hold me to it.
Keep the roadside assistance number on hand, just in case.
