Well my father used to own a camaro ss and land cruiser,the camaro maintenance was just slightly above in cost in comparison to the cruiser. The services are not expensive at all around 500qr for the normal service, but some people are concerned about spairs because they are almost in the "sports" category. Tires cost around 700qr per piece and other parts aren't too bad either, they can become expensive if you chose to make them by fitting branded brembo brakes, pirelli tires, sports suspension and other stuff.
