All the hooplah over the employee pricing for everyone is actually more perception than anything. I went to my local Pontiac dealer to really check this out - a 2005 Grand Prix GT with an MSRP of $25,600 has an employee price of $20,600.
When my step dad bought his 2003 Grand Prix GT, no special offers or gimics were on hand (forget financing, as he paid cash for the car). Mind you, this was still before the '04 redesigned GP's came out.....
The sticker was $26,350. He bartered between 3 dealers and got the sales price down to $21,000 even.... and then on top of that he added his GM card savings. So he essentially got the same deal by doing a little homework and hard work.
If people saw that the employee pricing this was just basically the price you could get the car for anyway with just a little work, it all of a sudden doesn't sound so fantastic.
My step dad himself said he doesn't see what so great about the pricing thing.
