I just got off the phone with my local LR dealership. Here are the prices he quoted on my '05 LR3 with 35.7k miles (he did say there is a price line at 36k miles...he said it before i told him what my mileage is):
Additional
yrs / miles
2 / 24k - $1600
3 / 36k - $2200
4 / 48k - $2800
This is actually for the GMPP warranty. He explained that the owner of this LR dealership also owns some GM dealerships in town, so they can offer it. He said that it is about $1800 less than the LR (Assured) warranty, but he can sell both. He said that he had asked about the differences in the warranties and specifically in servicing the warranties and said that he would try to sell the more expensive one if there was more value in it, but found that there really was no difference. He described it as bumper-to-bumper, excluding normal wear, just like the regular warranty. He also said this dealership will waive the $100 deductible when you purchase it from them and service it there.
I asked if he would be willing to negotiate price with a group buy and he indicated he would probably only come down $100 as he feels he has cut the price a lot already...but when I mentioned this board was actively shopping, he definitely wanted me to come back and tell him if i found a significant price difference in what you all found and then we can compare to see if we are talking apples-to-apples.
Since I am only a few hundred miles from hitting the price line, I will probably need to pull the trigger on this in the next few days. Let me know if anyone is interested.
