As a business owner, I can see the point of "customer perception". It can lead to the customer forming subconcious thoughts of overpayment for your product/service in a high profile vehicle that is profiled as a "Rich mans ride".
The region I live in is overflowing with $$$ and when I show up in my modest H3, I get comments from "good for you, you deserve it" to "You just had to get a Hummer didn't you". My customers do not realize that a F150 loaded up costs MORE than my nicely equipped H3.
It is all about perception and I choose to be percieved as a sucessful business person.
Your boss calls the shots, but I would stand up for your Hummer and spin the situation into a win/win for you and the company. Offer free "Thrill Rides in the Hummer" for the largest purchase of the week. Maybe some creative advertising with the Hummer.
Or you could just tell him the truth...That he should not have such a complex about his employees driving a vehicle that gets more attention than his...
I am of the opposite mindset. I wish I could pay all of my employees enough to afford H2's and H3's, then I could afford a H1.
