Here is some info I collected when I was looking for mine. The best (cheapest) time to buy is earlier as I think they an additional amount if your car is older than 1 year. I got mine from Larry Valdez for 1465$.
"I got a good price today at Stevens Creek Dodge in San Jose CA. Maximum Care (code M750G) 7year/50,000mi, 0 deductable for $1295. Claude Short Dodge wanted $1660,Woodhouse wanted $1685,and Erica at Fitzgerald Dodge wanted $1660. At least a $360 savings, **** good in my book. Talk to Larry Valdez at 408/248-1800, tell him Brad recomended him."

"I am a Viper owner and also a dealership owner...and haven't replied directly to this group for fear of sounding like a spammer. However, I will gladly beat all of those prices on Chrysler Service Contracts. They are a very cheap form of insurance for vehicles that are driven like ours! Send me an email, and I will gladly give any quotes. Thanks, Dwayne Saunders
