OK, so it looks like I'll be keeping my 2005 4.8is since the values have plummeted over the last 6 months - but not without an extended warranty. I have looked at a buch of them, and Auto Advantage seems to have the best price to coverage ratio -- their bumper to bumper coverage looks like:

$100.00 Deductible Per Repair Visit
3 Year/ 50,000 Total Odometer Miles- $1,332.00
3 Year/ 60,000 Total Odometer Miles- $1,526.00
3 Year/ 75,000 Total Odometer Miles- $1,815.00
3 Year/ 85,000 Total Odometer Miles- $1,964.00
3 Year/100,000 Total Odometer Miles-$2,194.00
4 Year/ 60,000 Total Odometer Miles- $1,694.00
4 Year/ 75,000 Total Odometer Miles- $1,916.00
4 Year/100,000 Total Odometer Miles- $2,555.00
5 Year/ 50,000 Total Odometer Miles- $1,554.00
5 Year/ 60,000 Total Odometer Miles- $1,749.00
5 Year/ 75,000 Total Odometer Miles- $1,906.00
5 Year/100,000 Total Odometer Miles- $2,699.00
6 Year/ 60,000 Total Odometer Miles- $2,045.00
6 Year/ 75,000 Total Odometer Miles- $2,395.00
6 Year/100,000 Total Odometer Miles- $3,105.00

Far better than Warranty Direct or Fidelity. So, Does anyone have any experience with them covering claims? I did a search but came up with very little... Any input would be very appreciated!
