The PPM can also back up your service history in case any warranty issue crop up. Then, it becomes your word against theirs as to the what, where & when intervals were performed. Along the same lines, the PPW (warranty) also goes hand-n-hand with the PPM. Its more piece of mind rather than a real bargain value item. I got both for two reasons:

1) It is much cheaper when you shop other dealers since it runs anywhere from $600 to as much as $1400 for the PPM from dealers. (I found out the hard way). The warranty was over $1500 cheaper thru Midwest Toyota (many ref's to them out there) and is still a Toyota warranty.

2) With so much in the Hybrid technology, and also all the little gizmos on the Camry Hybrid (mine is a loaded version) i figured that just to replace a heated mirror of power door motor could run almost as much as the warranty package. More piece of mind (again) that if ANYTHING goes wrong on the car - it's covered.

Most dealers try the tactics that after you walk out - you cant do anything. If they say that to you they lie! I would question the dealers honesty & integrity to back you into a corner to make a few bucks (quite a few) on you for undercoating, paint protection, and an inflated PPM & PPEW on the spot. Also, when being serviced the dealer is supposed to update any TSB's out on the car. If you do all the stuff yourself, they never see it.

In a nutshell - I find having the warranty and PPM is a convenience and assurance that if something does go wrong within the next 6-7 years.

Regardless - the least you should do is check out the plans online. The PPM may be more time critical since after the 1st 5K miles is when the clock starts. The ExtWarranty starts after your original 3/36 so anytime before then should be o.k. Keep in mind though that not every little thing might be covered under the 3/36 since it may be different then the extended plan.

Enjoy your gas mileage!
