I've got a couple questions that hopefully won't be too hard to find the answer to.

1. Is it typical to have lots of road noise when driving at highway speeds, I notice it a lot from the back tires (especially with the new v-rated tires)

2. I find that the car likes to wander over the bumps, ie. the steering wheel wants to turn significantly as i cross over the tire grooves in the road.

3. Musty sort of smell from the heater which fogs the windows but no leaks from heater core?

4. Noisy suspension when going over larger bumps and potholes

Any answers that anyone could provide would be awsome

Thanks!
