Why a car that made in 2008 ,its model year is 2007?

Because you have the model that was designed in 2007 and produced in 2008

Of course it is possible. The production date means it was MADE in the year 2008, but it is an older model from 2007. l maybe wrong ;)

Usually it is the other way around -- the [next year's] models come out in the fall of the [current year]. Lately they have been coming out earlier & earlier.

What is means is: Your car may be listed in the ''books'' (Kelly Blue book, NADA, etc.) as a 2007, so it is value will track the 2007 models, but what u will end up with is a 2007 with the lowest possible mileage, which means it will command the highest resale value of any 2007 (''top book value'').

In some cases u may even be able to sell it as a 2008 vehicle.

Its possible. They do not stop the production line on Dec 31st and start making different cars on Jan 1st there will always be some overlap of years and models.

That is not uncommon. The 2006 Lexus GS came out in early 2005. The model year is just that, the model is year. The production date is a completely different thing.

just the way things happen. times if you special order some thing a while back will make this happen.
