When you buy an extended warranty, the warranty time begins counting down IMMEDIATELY.
Thus, buying a new viper and a 7-year extended warranty at the same time means you get 3-years of new car bumper-to-bumper warranty, followed by four years of extended warranty. 7 years total.
Buying a new viper without an extended warranty, then buying a7-year extended warranty just BEFORE the bumper-to-bumper warranty runs out, means you get a 3-year bumper-to-bumper warranty followed by 7 years of extended warranty. 10 years total.
The reason extended warranties are so cheap with a new car purchase is because the extended warranty is useless while the bumper-to-bumper warranty is in effect. Thus, you are effectively buying only a 4-year extended warranty.
This is NOT my personal experience with the Chrysler Maxicare 7 year warranty. The Warranty on my 2008 Gen IV ran concurrently with my factory warranty and expired exactly 7 years from the purchase date. I purchased this warranty more than 1 year after I purchased the car. Perhaps the rules have changed, but I doubt it.
What's incorrect? Seems exactly what you stated. The Extended warrantee run concurrently with the factory warrantee. The only benefit would be if you were able to buy a Max Care 7 year plan at the end of the 3/36 factory warrantee and have it take effect at that time...not roll back to the original date of service...in effect doing what Thom originally posted.
