My car has started making funny scrapping noises whenever it get up to about 65 mph, or at slightly lower speeds if the car bounces a lot from anything.

Obviously i need to take it into the shop, but i'm not sure when i should do that, especially since my "regular" mechanic is in Costa Mesa/Irvine. Which wouldn't have been quite so inconvenient in a week or two but rather sucks now. If i'm really lucky they'll be open on friday so i don't need to worry about work, presuming that it's okay to keep driving the car at the moment as long as i keep it to low speeds =/ However i suspect that i'm probably going to have to end up taking it in tuesday or wednesday morning and make up the time later.
