As Mike said, check the year by serial number. In 2000, Max just changed the body style which is easiest to recognize by the square headlights instead of the older round lights. The newer style also has the engine cover completely covering the engine instead of letting the air box stick through a hole, and the back seat has 3" more legroom which is the biggest improvement. A 2000 model will have a serial number right around 16200 or so.
The 18hp engine is "OK" for 26" tires but it is the minimum. Underpowered for factory tracks but it will get you there... slowly.
Everybody dies, but not everybody lives.
