Hi BCredliner.
I sold new cars for a number of years. Everything we did was to make $. I stopped selling cars because of the industry. A lack of morals or ethics abound. I could not be part of it any longer. So, I then sold yachts. I experienced a whole new lack of morals and ethics. I stayed even shorter amount of a time.
My point was yes, they pointed out good things but not one of the big 3. At this age/mileage, they should have asked I think, if they cared about the life of the rig or my wallet.
The "salesman" is anyone trying to get you to do or buy something. In life, we're all salesman if we try to convince another. I just urge people to understand the motivation of a suggestion before blindly going forth. This same BMW dealership charges my "brilliant" sister-in-law a hefty sum to add coolant. I take care of her car now but they also convinced her that she needed to buy brakes (disk and pads) every time she bought new tires. She didn't mind because they gave her a loaner for a few days. Not a great trade off in my opinion but it worked for her.
My car having an "m" badge on the back when I bought it and today when it's not an m5 reminds me that I forgot to question the sellers, friends of ours, and got duped. I was so sure it was what they and my "mechanic" said it was that I paid full retail. I'll change the badge once the build is complete but for now it's my badge of shame.
