| I probably added about 200 lbs. It seems like a lot, but it's only about 5 percent of the weight of the car. Roughly equivilant to one large male passenger. I can feel the difference (just as you could feel the presence of a passenger) but it's not that severe. So far, no squeaks or rattles. The work was done by very talented guys at a local shop, and I monitored all stages of the process. Since I used brand name Dynomat, the cost came out to be quite high. Just under ten grand. But it's quieter than any production car on the market (according to Car and Driver's reports on noise levels at 70 mph). I've been satisfied with the sound proofing work and if I had to make the choice again, I would definitely do it. However I think most of the effect could be had with about half the cost and weight. I'm working on getting the dual pane windows made for it, which should make a significant difference, if I ever get it done. I drove the car around stock for a while, and I have to say it was a fantastic machine for the price. The insulation work just brought it to a new level in terms of peaceful high speed cruising.
Those Fleetwoods are HUGE!!! I rode in one once and thought it was awesome. I thought about getting a late one instead of my DTS but living in DC half the year, I just couldn't deal with the size. Awesome car though.
