THE best finance guy around Mario

Amazing experience. Mario sold me the best BMW ever. Mario and the team are amazing. I work at a local coffee shop and they still come in and order drinks from me, 7 months later. They are people that truly care about the buyer and not themselves. I had been to three other auto sales groups in Atascadero, they are all kinda shady, unless it's Guarantee Auto Group. Mario got be the lowest interest plan available. Would recommend this group any day. They buy great cars. I will be buying my next German car there.


A bah-humbug outlook changed when impulse took me to Guarantee Auto Group and i finally found the car I've been looking for! Mario Sanchez sold me a very well priced locally owned car. I am so impressed that i am happy to be able to give his business five stars!


I had been to other dealerships in the area looking to upgrade and no one was able to do what Mario did. I was upsidedown in my current car loan and wanted out. Mario was able to get me much more than blue book value on a trade in and get me out of my loan. Plus he got me approved for my current loan at a good interest rate with a 2 year warranty and GAP insurance. I upgraged from worn down 2004 convertible with over  100 thousand miles to a beautiful 2006 Chrystler 300 with 60 thousand miles plus warranty and gap insurance and my payments barely increased from what I was currently paying. I waited a few months to post a review, its been 4 months and im still just as happy as the day I drove off the lot.
