I have a 1999 SL1. The car is vibrating a lot at 60 mph or more. The car is very loud as well (not the engine). I will likely take to car to a mechanic soon, but I'd like to get your advice first. What is most likely to make the biggest difference: struts, control arms, coil springs?????
The tires are in great shape, so that's not an issue.

I appreciate you folks helping out.

I'm thinking tire balance, CV joints, wheel bearings, engine/transmission mounts or a combination of any of these.

Thanks for the advice.
