Total Bullshit. they estimate 5 years to pay back, based on 20,000 KM year. Total for 5 years is 63,000 miles. The warranty on hybrid components here in California is 150,000 Miles. Assuming you drive the car until they stop repairing it for free, you'll get a payback that is 2.3 times great than their reporting.
Matrix Vs. Prius is 16,800 and 12,800 to maintain over 63,000 miles, to hit 150,00 miles, multiply by 2.3, you get 38,640 for the matrix, 29,440 for the Prius, which is still at this point under warranty
You've saved $9,200 in fuel over the warranty period
MSRP for Matrix is 16,700 base
MSRP for Prius is 21,400 base
total savings is Matrix Base cost+Extra fuel cost-Prius base cost= $4500 Not a lot, but Nothing to scoff at either, plus, the Prius has better resale value, more standard options than the Matrix, is bigger, safer, and better rated.
Prius fun factor is 0 though. :-(
