I've had good and bad experiences with both. Though the only time I was ever out and out lied to was car salesman. I was mailed an offer to buy a new car at a particular price with a promise of my current car being a trade-in for a particular price. Lamb to the slaughter, I know!, but I went anyway.
Long story short, they told me they couldn't honor my mailer because my car had a salvage title. Offered me $1,000 to "get it off my hands". I went home incredibly upset, because I knew I hadn't bought it as a salvage title. Was on the phone with the bank, who had my loan and therefore my title, multiple times the next day trying to get to the bottom of it. Got so upset and wasted a lot of time for NOTHING. My title was fine. It was not a salvage title. They were just trying to steal my $7K car for $1K.
Ironically, the salesman who sold me the (above) car I am talking about four years previous to this, was absolutely fantastic. I was nervous about my credit and knew they had a special in-house credit financing. But when I told him my credit score, he told me NOT to use their in-house financing because that was more for really low scores and mine was fine. He asked if I belonged to a credit union and, when I said I did, he told me my best bet was to get a pre-approval from them. I mean, seriously?!? A car salesman who actually sent me OUT of their dealership to get my own financing because I would be better off that way. I returned the next day...preapproval in hand...and waited for him to buy the car I wanted. Which he sold to me at below wholesale blue book price. I have referred countless people to that dealership and him specifically.

As for REAs, although my experiences have been limited, they have primarily been awesome. My first REA really held my hand through the process. I was a first time buyer and buying a duplex, to boot. There were a lot of ups and downs and she really went to bat for me. But then, like many of you had mentioned when talking about good agents, she has a stellar reputation in the industry and has been in business for over 25 years. She has a steady stream of clients and referrals.
The only bad experiences I've had...and these are fairly minor...are agents who seemed eager to get my business. But then don't call me back in a timely manner (or at all) when I have a hot lead on a house I want to view.
Also, when I was displaced in Miami after Hurricane Katrina, I contacted an agent about finding a short-term corporate apartment...which he had specifically advertised was his specialty on a CL ad. Yet, even though he knew I was only in Miami temporarily and I had already explicitly told him I did not want to buy a condo...ALL he wanted to talk to me about was these "great underground" deals for below market prices on new condo high rises going up.
So...wait...let me get this straight. I need housing NOW. I've told you I don't want to buy real estate. And your answer is to sell me a condo I couldn't even move into because the development is still being built. Am I understanding that right? Did we just land into an alternate reality where the words I say suddenly have a totally different meaning from what I think they mean?
