I came from Columbia SC to look at a Jeep Sahara I saw online. Greg greeted us at the door and got us into a test drive and then purchasing the vehicle without any issues. He was friendly, efficient, and made my car buying experience a breeze. I would recommend ALM Marietta to friends and family, and ask for Greg!!!

Scott S.
Scott S. was a great help to me with the sales team. Met Scott for a test drive, and he was very knowledgeable and helpful without being pushy. The service department had to work on the truck I was interested in before it was ready to be sold, and he kept me updated and informed throughout the process. Although I ultimately bought a different vehicle, it certainly had nothing to do with Scott. Would happily reach out to him in the future or recommend him to anyone else in the market.

Pay attention what get in your hands paperwork throughly
Pay attention what get in your hands paperwork throughly read it carefully and see everything they put in it such extra extra cash that you didn’t say and extra money makes it go up higher that you can’t afford the extra payment.Now you see how much gap insurance $$$ added in the paperwork and makes sure you get a lawyer go with you when getting used filthy car full of dog hairs.Makes sure you have mechanic on hand too.They will sell you a car without license which is illegal.Don’t use no co-signer.Don’t use Ally financing on new or used vehicles.Even if you pay it off tell you getting gap refunds on mailing letter.they will keep it cause you don’t qualify for it.Keep up with all your paperwork in a file and payment history on papers like print out.Get your payment down as low as you can and 84 months is long ways to go.Do research how to save money on used or newer car without all that crazy extra add on.They’re trying make money of of you even on the elderly people.Have a great day everyone
