Horrible shady salesmen.... I was in the middle of a deal there today. I was buying a car for my daughter, I took it out for a test drive and decided that it was the perfect car for her. When I returned back to the dealership ready to sign the papers, I found out that while I was out for my test drive they sold the car to another customer. HORRIBLE! A customer that came after me. I was first inline for this car, shouldn t I have had first chance to buy it?
Are the salesmen at Red Deer Toyota this hard up for a sale that they need to stoop so low? Was this a friend of the salesmen? Greasy if you ask me... I will NEVER buy from them!
