The 2003 Volkswagen Golf GL is a relatively easy vehicle to maintain, and a good choice for someone experienced in vehicle maintenance. The components of the spare tire are easily accessible in the rear of the vehicle. This keeps the tire and jack kit reliably access in case of emergency. Checking the oil level is no problem, as the oil dipstick is easily accessible in the engine bay. The engine coolant reservoir is easily visible in the engine bay. This will allow you to check and replenish the fluid level on a regular basis.
Some things are more problematic on the 2003 Volkswagen Golf GL. You will have to remove the battery in order to access the headlight on one side of the vehicle. This is more difficult access than you will usually find. To change the front wiper blade you will need to use a tool. Other models do not require the use of tools to complete. Changing the engine air filter will require you to loosen screws first. This will require tools you will not usually need to complete this.
