On our way to Death Valley, we got a flat in a rental. Since we didn't purchase the rental insurance, we had to fix it ourselves. We headed back to Las Vegas for a repair and called a few places, but ultimately decided to go to Superior (on Sahara) after speaking with Jon. We were helped by Tim (the manager) on arrival. Both guys were personable and knowledgeable. They were honest and knowing our situation, they didn't try upselling us anything or ripping us off. As soon as we got there, they took our car in immediately. Within 10 minutes, the tire was changed and we were on our way. Next time we are in Vegas and have a problem, we will definitely be coming back. Thank you Superior!
