Buying used SUV. NEED HELP!!!

[carbuyer2]

Guys, my wife and I are going to buy a used SUV to replace our Nissan Altima. We recently had our first child, and we have to have the extra room as we travel to my in laws quite a bit. We have found 3 this week we are interested in, but I need some expert opinions! As you all know, asking price is not what we'll pay, but I am going to include the dealers listed asking price just for reference. Thanks for any help!!!

First off I would never buy from a dealer unless I know the owner personally. They will rip you off in one or more ways while you go off thinking you got a good deal they are sitting in their office laughing at how they got over on you. I worked as a line mechanic in dealerships in my younger days & sometime the sales people would come into the shop lunch room laughing about how they stuck it to someone.
Buy off of Craigslist, Ebay, your local rag paper etc. You save a lot of money that way. Private sellers lots etc.
Go to Kelly Blue Book on-line figure out what you want, mileage, options, etc. look up wholesale & private party in GOOD condition not Excellent Find a price in between as the price you are willing to pay & stick to it. Never be in a hurry on any deal. Have CASH in hand. If you have to make payments take care of the financing in advance from your bank, credit union.
Good deals can be had from Rental Companies. Many Credit Unions finance buying from certain rental companies. Sometime you can buy what you want right at the Credit Union you belong to.
I buy all my vehicles used for Cash. Buying for cash saves big dollars on insurance also.
