Is There A List Of All Car Makes On The Internet

What are the ONLY differences between Audi Q7 2008 car line-up models?

I need a list for the differences ONLY please. The Audi 4 line-up models are:

-Q7 3.6
-Q7 3.6 (Premium)
-Q7 4.2 (Premium)
-Q7 4.2 (S Line Model i.e. Sport line model)

They must be 2008 year models not the previous ones.
The differences can be on everything such exterior, interior, engine, gps, multimedia, ..etc

When buying a car, what's the difference between internet price and sales price?

It's a list price for the vehicle. In other words a full price and the price they are offering the vehicle for sale to you. Both numbers might be artificial - not related to anything. It's all about making you think it's a great deal.

As always it is up to YOU to determine what a good price is to pay on any given vehicle.

You should always try to negotiate your best price on any vehicle purchase. If you are not satisfied with the price that is negotiated, then walk away from the deal and try again another day or at another dealership.

How come everybody makes fun of NASCAR, but not other MOTORsports like IndyCar, NHRA Drag Racing, etc.?

You are always seeing buttholes make fun of NASCAR everywhere on the Internet, saying all that crap like it's just going in circles and turning left (WHEN THEY ACTUALLY DO TURN RIGHT TOO AND DON'T ALWAYS RACE ON CIRCLE TRACKS), saying it's only for rednecks and calling the drivers rednecks (FACT: ONLY 9 NASCAR DRIVERS ARE FROM THE SOUTH, 7 ARE FROM CALIFORNIA, 2 FROM WASHINGTON state, 2 FROM PHOENIX, 3 FROM NEVADA, and many from the Midwest, northeast, etc.). And they also say it takes no skill, and it's not a sport. Well for one thing, the cars are not a thing like the car you drive, they're much heavier and faster and you must take so many G Forces it's not even funny. And, of course NASCAR isn't a sport, it's just a sanctioning body holding the MOTORsport of auto racing. All these different kinds or racing are called motorsports.
Now, that's what I don't get. People always say these untrue things about NASCAR, but they never say those things about all of the other kinds of car racing and never make fun of the other kinds or racing. They always bring up NASCAR when there are many other kinds of great auto racing that they could make fun of, like IndyCar, NHRA Drag Racing, Formula 1, Grand Am, ALMS, Arenacross, Motorcross, Rally cars, touring cars, and there are so many more, but out of all of those, the only one people aver make fun of is NASCAR, the only one people ever say crap about. Why is that?
