How much does a used car value drop after a new generation is released?

Im looking to buy an 06 Lexus GS. I know a new generation of the car is coming out this upcoming year. I was wondering how much would I save if i wait til the new generation comes instead of buying now.|||It won't matter. The '06 GS isn't the current generation anyway, but rather the last year for the GS300 (replaced with the GS350 in 2007) and second to last year for the GS 430 (also transitioned to the GS450 in 2007).





Any value penalty there would have been in terms of book value occured in 2007 when the next generation came out. Two generations ago - no penalty at all.





The biggest hit to used car values tend to be to the pretty new ones, immediately before the next ones come out. For example, the value of a used 2011 GS350 will take a hit this year as compared to what it would have been since they are releasing an all new GS in 2013 (I don't think they even bothered with a 2012).





But for a 2006 - don't worry about it. That ship sailed 5 years ago when it was replaced in 2007. GS 2006 prices won't change at all now, as it's not the current generation anyway.





Good luck!|||Value is a "market driven" thing. You will need to check the published trends from KBB, Emonds, and other reputable sites tracking Value. Your financial institution along with many other companies you can find with a Google search also track this information.





There is no set standard or guaranteed method to calculate this as it totally depends on supply and demand plus safety and a few other factors as to how a car maintains is value.





If you look up a certain model that is been out year after year after year, you could at a minimum track normal change with that model. The normal change would only suggest with it might be and not what it is going to be.|||Vehicles values are so unpredictable. The value of any vehicle is generated by the market demand and not by any book like NADA, Red Book, Kelly BB etc.





A Lexus, BMW, Benz, Acura will always keep the value high no matter what generation comes next.
