I just got my 98 XK8 Coupé. So far I've noticed three problems: - a metalic noise coming from the passenger side rear wheel when driving at low speeds - a wind noise coming from the same side rear window above 45mph - when trying to fill up the windshield deposit the liquid started to came out from underneath the car What do you think can be the cause for each of these problems? Thank you very much, and a Happy New Year.
