Got to love it. There are an awful lot of people out there that have so little self awareness that they believe what others say even when it goes against their personal experience. In a word, lemming.
Sorry if this is offensive, but you need to use your brain. If you have a vehicle that is trouble free, does what you ask it and does it well, why would you care what someone else has to say about it? By the way, if you have not had your Jeep flashed, do so. It drives so much better.
Now, if you are bored with the car and can afford a different one, go for it. It is your money.
I associate that behavior with all Honda dealers as the ones around here are just as arrogant. The only ones worse are the Acura dealers. I wonder if they learn it in their training classes...
