troubadour

I had the cabin floor area done, too, yesterday while they were putting in the remote start kit. In driving around, it seems to have made a small difference, although I could be fooling myself since things are down to the finer shades of gray now. After replacing the tires, doing the sound treatment on the back, doors, and floor, I would rate the soundproofing something like this as to bang for the buck:

1 - Tires
2 - Back (Hatch) Area
3 - Doors
4 - Cabin Floor

I also had them raise the back mounts of the passenger seat by 1 inch. They got longer bolts (factory bolts were too short) and fabricated a slightly-sloping spacer to do that. About an inch is the amount of adjustment of the rear knob on the driver's seat, and the seat is more comfortable now. My wife swears it went up by at least a couple of inches - and she is thrilled to now see over the dash! I rather passed off how much it was raised with somethiing like "As long as you're happy...." But that 1 inch did make some significant differences even if some of it is "apparent" to the person involved.

I'm quite happy now. The car is reasonably quiet, we can carry on conversations, and my wife (and I as well when I sit in that seat) is happy in the comfort and improved view of the passenger seat. The remote starting (something I've had on many cars) is great as always. Love the car, and it's really fun to drive - which was the whole idea.
