Windows=  Hummer H3

• The car comes in many different versions with different prices and features. Extra features such as brakes, steering, and seats will require a more expensive version of the car.
• With each upgrade, the car will become slower, bulkier, and less efficient.
• The car must be registered with the Department of Motor Cars the first time its engine is started. If for any reason this registration does not take place, a thirty day grace period (exactly 720 hours) will begin, immediately after which the car will cease to function.
• When the car is purchased, it is registered to a single driver. Only this driver will be able to operate the car.
• 80% of parts and accessories are designed solely for this car. However, parts older than five years are not supported.
• During high-performance driving, the car may stop moving or stall. The only way to recover from this condition is to shift into neutral, roll up all of the windows, and stop the engine. If this is not possible, the engine may be stopped manually by holding the key in the “START” position for three seconds.
• All repair and maintenance is handled by a third party in a foreign country. This party will not repair the car, but tell the user how to do it himself.
