The 2008 Opel Corsa D is moderately difficult to maintain. To reliably access the headlight you must completely remove the air filter housing, which will require many tools to do. Changing the cabin air filter will require you to remove the entire glove box first. You will have to completely remove the rear tail light housing for access to the tail light bulb, as well, and the tools necessary may not be readily available.
Some things are not a problem on the 2008 Opel Corsa D. Changing the fog light is easy, as you only have to reach through the bottom of the vehicle for access to the bulb. The engine coolant reservoir is easily visible in the engine bay, allowing you to check the fluid level on a regular basis. Monitoring the oil level is no problem, as the oil dipstick is easily accessible in the engine bay.
