This is an age old question. Do I invest X dollars in my (fill in the blank product) in order to get it to live a longer life or do I step up and replace my (fill in the blank product) with the latest and greatest product offering? This is relevant for your home's HVAC system, your personal vehicle, heck, maybe even your blender.

Let me tell you what happened to me the other day... I was at one of those self service car washes getting the pollen off of my car and giving it some long overdue TLC. After I was finished cleaning every surface, nook and cranny, I cranked the car to leave, only to hear a funny sound. It was one of those sounds that I couldn't place, but was sure my car shouldn't be making it. The thought that popped into my head at that moment was, "HOW MUCH IS THIS GOING TO COST ME..."?
