The Salesmen with their checkered jackets...bow tie and polyester pants have all been replaced by highly trained sales consultants, loaded down with computers at their finger tips... there are no used cars anymore - they are now all pre-owned gentle vehicles

But one thing that has not changed is the negotiation process.

Buying Private VS Dealership

With a dealer, you have recourse. With a private purchase you have little or none, with that said, lets look at the pro's and con's buying private.

Buying privately is simply buying "as is". When you purchase privately, you're buying a car exactly as you see it .... any problems the car has become your problems. When someone's about to sell their car, it's usually because they're buying another or seller not being satisfied with trade allowance from dealer.

On the negative side buying privately

If the vehicle is found to be stolen, then the buyer is out of luck. The law says that a stolen vehicle returns to the original owner. The buyer loses the whole purchase price, and would have to sue the seller, who by then may or may not be able to be found.

There is also the risk of liens being registered against the vehicle. Any liens that are found to be registered against the vehicle would then be the responsibility of the new owner ... they would have to either pay out the lien, or face repossession of the vehicle by the lien holder or The vehicle may have had prior accident damage, and the buyer would have little or no recourse.

On the positive side buying privately

There are many good deals to be had, sorting them out is the problem as there are also a fair amount of scams, the number one question is finding out why buyer is selling and having trust in the sellers answer.
Example, good answers are - leaving country - retired cant drive anymore - getting a company car - don't need a second vehicle anymore, other good buys could be worth of mouth, but beyond that it becomes buyers beware dealing with a total stranger and buyer better having done some homework making sure not having a lemon parked in the driveway.

Buying a Vehicle Privately with a Registered Lien

Never surrender payment directly to an individual seller under a verbal promise that the loan will be paid off and the lien released.

If you will be paying cash for the car, you MUST pay the lien holder the loan payoff amount and pay the balance " if any " to the seller

If you will be financing the vehicle, the lending institution will fund the lien holder and transfer lien to it's holdings along with title.

Should you have issues with transfer of title or registration that you do not fully understand, contact your local    DMV.html

Buying from a dealer

When consumers buy a vehicle from a registered dealer, they are protected by numerous pieces of legislation, such as the Sale of Goods Act, the Consumer Protection Act, and the Business Practices Act, to name a few.
By law, dealers must guarantee title against stolen vehicles. Also, dealers must guarantee that there are no liens on the vehicle. They must use Bills of Sale that abide to the law, and are required to report all known material facts about the vehicle.

Here are some services a dealer provide that a private seller can't.

A Dealer's Warranty
After Sale Service
Recourse
Title Guarantee Against Stolen Vehicles
Financial Assistance
Extended Warranties
Lien Free Vehicles
Trade-Ins

It looks the safe way to buy is from a dealer, but they are not all angels and knows every trick in the book to have the upper hand. there are hundreds of scams being used by some dealerships, as an example I will use one that ties in with this post and I am almost 99% sure you would fall for it.

Note... above where it says...by law dealers are required to report all known material facts about the vehicle... thats true provided the buyer asks and most consumers don't, but now comes the know it all buyer whom has done extensive research and demands a history report which contain several pages...well, I will admit he/she has done all homework if the numbers of pages were counted in order and not a number missing in the middle 
not many dealers are scum to this extend, but in my time I have seen this little trick work a few times.
