I know Chrysler offers 100% refundable Max Care warranties for about 15% more than the standard ones. The catch is - you receive the full refund if you had no claims and the timeframe has expired. Example - 5/50 warranty with a 1/1/05 in service date. On 1/1/2010 if you have not exceeded 50K miles and have had no warranty repairs, you receive 100% of your purchase price of the warranty back.
