Used Cars Can Sensible Choice
If it's an aluminum system check for corrosion and epoxy around the tank joins. Aluminum radiators need special coolant. If it's not used they will corrode rapidly and begin springing pin leaks.

Keep in mind, guys, that the men who do usually have a lot of confidence are usually arrogant and ungentlemanly. Not all of them, of course, but the majority of them. You can show her you have Special Confidence and that you are not a jerk.
Let us start with ease of obtaining. Obviously newer car parts will be easier to get than older ones. A friend of mine still has a 1975 Pontiac Lemans. To obtain parts for this car he has to literally go to junk yards and even online. No new car dealers keep parts beyond 10 years or so and even auto parts stores limit their inventory to cars under 20 years. A 30 year old vehicle is almost impossible to find parts for. Plus, if you can find the part, depending on where you get it, the cost could be anywhere from 20 to 100% over the original part cost. To say that late model car owners are taken advantage of would be a gross understatement.
I had no trouble finding a rock pile. Hitting the snake with a rock, in the head, was another matter. The first rock hit the snake on the back, behind the stick. The next rock hit the stick. But, the rattlesnake never had a chance. Robert's grip on the Y stick held fast. By the time I had exhausted the rock pile, both the snake's head and the mouse were nowhere to be found.
If a particular junkyard does not happen to have the part you are looking for that day, they can make a search through a computer network especially for marketing mistakes and locate that part in seconds.
There are salvage yard in most cities or towns, and they sometimes have decent deals. The problem is that their inventory is usually fairly limited. A salvage yard near you might not have what you are looking for, but another yard 100 miles away might have it. The problem is that you can't keep track of the inventory of all of the surrounding salvage yards and wait for just the right model to show up. What you need is a centralized place to look at the inventory of many different sellers and the ability to buy quickly before somebody else snatches up the car you are looking for.
It is also a find for the other end. The companies that have the parts have much more of an opportunity to sell what they have through an online source as opposed to people coming to their market. This opens up a whole new customer base for them. So both parties benefit from an online search engine.
