Most dependable truck i ever owned.
This truck is a beast, but with the Duramax diesel engine, its fuel efficient as well. my best average is 21 mpg which is insane for a truck this size.

Nelson Mazda Tulsa was very friendly and helped with what
Nelson Mazda Tulsa was very friendly and helped with what vehicle I wanted and walked me through with my purchase of said vehicle. The dealership was awesome.
Loved the Duramax Diesel and an incredible truck
Incredible truck. Wanted to trade it in for a 2020 same truck but unfortunately the interior for this year hasn't been updated. Supposed to next year. Will check in then. Would never consider a Ford or Dodge over this powerhouse.

Dan and the Best Deal family were AWESOME 👍 You can test
Dan and the Best Deal family were AWESOME 👍 You can test drive vehicles w/o someone you don't know riding along blabbing and increasing your anxiety. Vehicles I test drove were very clean inside and out. Another dealership in town will ride with you and the car I test drove was disgusting on the inside. No one will push you, call you, or harass you 💯 I felt at ease with the whole process. Eleanor is sweet and makes you even more relaxed with the buying process and paperwork. I love my new car Fiona and would definitely buy from them again! Dan I still want your signed Pic on your wall 😄 Thank you to the Best Deal family for such a great experience

I liked how they didnt play the "let me ask the manager"
I liked how they didnt play the "let me ask the manager" game all day, that tactic is exhausting. Jeffrey and John worked a long time trying to get me what I wanted and within my budget. I know I was driving them crazy, but they stayed kind and professional! Everyone I dealt with was great! Shout out to Jeffrey, John and Nick. This is my first Nissan and I love it! I hope their service dept is as good as the sales and financing department.

Excellent Service all the way around.
Excellent Service all the way around. Maintenance was completed in a very timely manner. My initial appointment wasn't until 10:30 am. As I did not have any particular things going on so dropped it off at 8:30 am and told them that they could keep it as long as necessary. I received a call at 9:30 am stating that all maintenance had been completed, an our before my scheduled appointment.
