If the check engine light stays off for the next 75000 miles, maybe it will be worth it. I have a diesel Colorado. The warranty and extended warranty expired at 60000 miles. The truck now has less than 63000, and I have had to replace two sensors in the exhaust, at a cost of over $550 in PARTS, labor being another $$300+. The first sensor was done at a local shop with a labor cost of $70, while the Northwest Hills labor cost was $240. I assume, hopefully, that the expensive labor was due to a more difficult job, but I am skeptical. I am very disappointed that the truck has been so expensive to own.
