Find Mazda Dealers in Boring, Maryland

Hey guy, I was in MD helping my sister to buy a car within 5 days. I picked the 2010 Mazada3 cuz my mom doesn't like the look of the civic nor the interior of a boring corolla. we own 2 Honda Accords so this was a change. Unfortunately the Mazda dealerships in this area were not very honest. They made up random fees and programs to try to trick you to pay more. 4 days before I left MD (Nov 11th) I requested online quotes from dealerships via edmunds.com. One dealership is willing to offer 17,800 for the car. Since there is a dealership name "congressional mazda" on Rockville Pike, MD right by my house (which they called and emailed me back without a quote) I decided to see if they would do a price match. After i took a test drive, set down with the internet salesman, he gave me as offer of the MSRP... (he got to me kidding me where is my internet quote?). I took out my iPhone email and said "Hey look, this is what I got from other dealership, can you match that?" he said, "damn, that's a very low number, I can try to see if my manager offers that." then he added "I know how this dealership do business, they charge you 400$ dealer fees on top of the processing fee, I would not lie to you and we only charge an 100$ processing fee that's it." He came back and said "our manage would match it and we cannot go any lower". I asked him give me a OTD price please, he gave me a TTL 18,850$ = 17,800 + 750 destination + 300??. I was very confused at first because 17,800 + 750 = 18,550 not 18,850. What is that 300$? I asked. He said "if you compare to Apple to Apple, we need to compare the fees too you know" he told me he would minus 100$ so the "fees" for you would be 300+ 100 processing + TTL + tags I asked him then "why would I want to buy from you if you would charge the same fees, plus can you prove to me that the other dealer charge that 400$". He just kept on saying Apple to Apple, Apple to Apple, he did not willing to take that 300$ off. I told him "I would have to think about it, I appreciate your time." and I walked out. It's not that I am poor and not willing to pay an extra 300$, I just found it's very unreasonable the way he does business. Apple to Apple my *beep* Anyway my OTD price from "congressional mazda" on Rockville Pike, MD was 20,350$. I ordered my car from other dealer but my family havn't picked it up yet. I will post my experience with this dealership after we pick up the car.

I'm too scared of the non-replaceability of the radio in the Mazda3 and too bored by an Accord, so the P5 it shall be. The quotes I'm getting so far are invoice price before rebates, so basically $2000 under invoice, and $14,825 with automatic but not much else. All before taxes, title, license, blah blah. I live in So Cal. Can anyone comment if these are good deals? Or should I negotiate with dealers in other regions? Richard
