I went into look for a certified used RAV4. I negotiated a car price for the car I wanted but when the sales person returned with the cost converted to monthly payment, I realized the cost was $20~40/month higher than what I had calculated and I challenged him on that spot. He admitted that his price was for some reason miscalculated and my calculation was right. I asked to quote for another car and he "accidently" calculated wrong (of course higher) again. The manager came out and had the audacity to still sell a car to me and wouldn't let me leave. Do not be fooled by them, know how to calculate monthly payment (google it) and always double check. Their trade in valuation is extremely low, I was able to get $3000 at another dealer compare to what they had offered ($500).
