If I were to purchase a 07 stock from the dealer that's been sitting on the showroom floor for the last 2 years, what will it need other than an oil change?

 

Sounds like the dealership needs some help.

And yes, do the oil, possibly a battery if they dont maintain it.
You could do all the fluids if you wanted.

 

i would do all fluids just for peace of mind.
why spend al that money ona car and be worried.

 

Yes, all fluids -

Motor oil, transmission, differential, brake, clutch. You need to be careful with dealerships and clutch/brake fluid changes though - typically they just change the reservoir fluid. Coolant should be fine, but check the level if any evaporated.

Also, check the year the tires were made - if they're 07s you're good, but if they're 06s they're borderline old, seeing how we're moving into 2009.

 

Typically any new car is fully serviced prior to the sale or specify you want the car fully serviced as part of the sales contract.

 

I see, if I were to pay for a total flush by myself, how much would it roughly cost?

Good call on the tires because they could add to the cost quite a bit.

 

Usually the dealer will follow the service schedule even if the car sits on the lot.
