Natural Negotiation for Engineers and Technical Professionals
If you are the buyer, an auction may be a viable way to obtain what you want at a decent price. EBay is one such auction, but beware of the downside of any auction and do not get caught up in a bidding war where you pay more than an item is worth. People are competitive by nature; know your limit and stick to it.
Regarding automobiles and unless you are a dealer, do not assume you can get a better deal through an auction whether you are buying or selling. I have purchased automobiles though auctions, at somewhat elevated risk due to limited availability to fully check out the vehicle prior to some auctions. Auctions can be fun with the adrenaline and the high when you win at or before you reach your preset (researched) price. Auctions are negotiations. Regardless of what you may hear elsewhere for using any type of auction (online or in person), do not present yourself until near the end if you are buying. Otherwise, you simply invite an incremental bid that simply raises the price. Research the game to fully understand the dynamics of any auction by observing them before you enter the foray. This is especially true of those you attend in person; you must understand the terms, language, hand signals and gestures beforehand lest you will be taken advantage of by those more experienced. If embarking on this path, choose a knowledgeable mentor to explain the details and steer you in the beginning.
Although automobiles I have purchased at auctions turned out to be dependable with no hidden defects, however, I still do not recommend them for non-dealers. What I do recommend is buying from a reputable dealer, but first you must research the game and follow the other methods defined in this handbook. Using these techniques, you will have less risk and fewer competitors wanting the same automobile at the same time, etc. All of this can and will translate into a better deal. It works.
