I have very bad experience worked with sales rep Brandon and Malory Vicks is the manager. They give me a price for Honda CR-V ExL last night and I just went to pickup the car today and they are asking me to pay $1k extra. This is they way they are treating customers.
Now I walked out without buying car. Luckily I have my friend dropped and didn t go away so far and came back to pickup me.
Thanks McDavid Honda Frisco.
