A warranty to me, regardless of the product, is a means of understanding what the mfgr. thinks of his product. If he has a solid warranty and I am looking to purchase the item, he gets my bucks. Whether or not I exercise it is my option.
I just bought a $7200 lawn mower and upon making the purchase asked the dealer about the warranty. I told him that I am quite a ways from him and do my own work. Taking things to the shop is not an option for me....he answered with: "Good thought as we are 3 weeks behind right now in the shop" and this was in April. I asked him if I presented my purchasing paper work and submitted parts which I removed will you honor the warranty and supply me with replacements without having to bring my machine in? He agreed. Fine.
Note: On shop being full, this is a multi-product, high volume dealer in a metropolitan area. His business is bursting at the seams but expansion is out of the question due to the high cost of adjacent real estate...he is on a well used interstate highway. I don't hold that against him.
