CrankCase: I am unaware of a racing team & I don't have any purchase experience with Glendora Dodge but I will tell you what experience I do have.
When the first Challengers came out in 2008, they had a Silver SRT on their lot with a hefty 20K mark up. When I asked a salesman about the mark up, I got a smug shrug and no real answer other than "supply & demand". As far as I know, they still continue the mark up game but I haven't been there in awhile to confirm that.
Also, I drive by that dealership every day and I have seen the sales staff actually leaning on and sitting on and/or in the cars while they wait for customers to show. Coffee cups on the hood right next to their a$$. Just not a good vibe for me.
They do have a sweet FF SRT there right now tho.
