edmunds gives you an idea of what the car may be worth, but what I have discovered is people get waaaay to emotional over cars and salesmen feed on that. I bought my Honda almost 4 years ago from Rock Honda in Fontana, it was a cash deal. I had received internet quotes from multiple dealers and I played them against each other to see how low they would go. Rock Honda won. I even printed out their quote and took it with me to look at used cars priced higher. People held firm that their 2 year old car with upwards of 20,000 miles was worth more than I could pay new. I went new, although I have it firmly burned into my brain that a car is NOT an investment and loses value the instant you drive it off the lot.
I even stopped at 2 Honda dealers on the way to Fontana to see if they would meet the price. Not even close and then tried to convince me the low price was a scam and I would be sorry…..it was a long boring drive, but I saved thousands.
