ok im currently looking at cars to buy and i test drove a 99 prelude today and when i get the car over 70 km/h i hear a buzzing or humming sound from the back as if the tire is rubbing on the wheel well or something, i know its not the wheel touching the well but have no idea what else it could be . should i bother bringing this car in for an inspeciton or just foget about it and look for another car?
