haha, ass swell.
It's possible that Holmgren has a deal with another Dodge dealer, or the owner has a Dodge dealership. That would mean they could unload teh SRT-5 easier. You never know. Secor might be subaru only, and knew they couldn't easily unload da fasta. So they offered you less.
And Holmgren beating the price by $300 is nothing. that's like saying "and when you buy this mansion, your first roll of TP is on the house!"
Bottom line - There are lots of factors that go into pricing. and the way you were treated, while not correct could have been easily changed if you didn't walk in looking like you were a 14 year old. Oh, and did he really swear at you? I still find that hard to believe.
