I think you should be looking to pay between $130,000 to $150,000 for a vehicle depending on spec and condition. I have been tracking the price of the vehicles for approximately two years, and many Dealers have been trying to charge too high a price for these vehicles hence why there are so many unsold. It appears to me that Dealers are now prepared to negotiate sensible prices for these vehicles, and the Dealers that do not, will be left holding the car in the New Year. I too, like you, am looking to buy, but I am not prepared to pay unrealistic prices for the car. I would not buy one off Ebay as the sellers are often getting their friends to bid falsely in an attempt to push prices up.
Hope you find one soon at the right price.
The right price, is simply determined by what you, as an individual, is looking and able to pay. If you want a new one, as many of us did, the supply gets smaller each month, and in a couple of months should be gone.
For used, it is a matter of what condition you are willing to accept.
I don't how you arrived at your pricing range estimates, but if you want to find a mint condition 2006 at $130,000 or even $140,000, good luck, you will have to wait a while, as present market conditions do not support your prices. Or you will have to be willing to accept one with high mileage, mild abuse, or neglected condition.
Too high a price is one thing, but I do not see the basis for your low prices mentioned, particularly for a vehicle that most of us would consider worthy. $150,000 or thereabouts, used, now that is a possibility.
And one year ago, yes, dealers were asking over $200,000. And many were getting it. I'm not bitter - I just want you to be realistic. I paid under MSRP for a brand new, from a Ford dealer, 3.6 miles on the odometer, in the wrappers, semi-rare configuration FORD GT. A new car was important to me, so I paid what I felt was fair, what was the "right" price for me. I knew I would never be dissatisfied paying under MSRP.
Time will likely bring prices of used cars down, as time will also bring the condition of certain cars down also. But the new cars, they are a different ballgame. Some dealers are willing to take the risk. I am not sure how the pricing will turn out with the limited remaining brand new stock. But I didn't want to miss out, and never again have a chance to buy new.
Good luck. Be realistic or patient, and you will have the car of your dreams.
