Here's a tip: You learn to hate many of these private dealers with a passion if you work in a dealership service department. They claim to buy "all these cars" from your dealership, so they want free stuff and red-carpet treatment, and you make no money off of them whatsoever, since it's all "internal" work. Meanwhile, they rake in the profits of re-selling a car you've refurbished for them for nothing but sweat and aggravation while they tool around in your loaner car. When they come back for it, they claim you scratched their used car, since they spent about 5 minutes it picking out, without regards to every inch of the exterior.
Damn them to hell with a pitchfork: The general manager hugs them and I have to bite my lip instead of telling them to hire their own personnel and feck off. I'd see the same guys come in to Lexus week in and week out, so I learned to bravely run away like Sir Robin and let the newbies deal with them because they're slithering scumbags that invade the nether-regions of the dealership. Meanwhile, their customers actually hate these faux-dealers, since they get all sorts of lies and false promises that their sorry asses don't feel like assisting, since there's no incentive to do so.
