I understand being frustrated when shops don't offer the pay you think is worth it, but I'm surprised by how annoyed some people get.  
I think luxury cars are ridiculous.  I used to travel a lot for my job and I rented a bunch of cars.  Eventually, I got to the point where I had rented so often that they'd often upgrade me to the fancy-shmancy cars.  You know what I realized?  Cars are basically all the same to me.  I don't care about the different brands: the things that matter to me are how carefully the cupholder location was thought out (for me specifically, given how long my arms are and how I prefer the seat to be configured), and if there's a place for my purse.  Those rarely have to do with how expensive the car is.
So, when I see a commercial for a car and at the end they say "well qualified lessees may qualify for $599/mo", I laugh out loud.  But if people think that's worth it and want that car, more power to 'em.  I don't understand why the low ball offers from MSCs don't elicit the same chuckle and delete reaction that I assume the same people have when they see an ad for something they consider to be ridiculously expensive.
