⭐️⭐️⭐️⭐️⭐️ A Truly Outstanding Experience! I recently purchased a 2024 Chevy Equinox, and I couldn’t be happier with the entire experience. My salesman, Jimmy Mack, was an absolute standout I recently purchased a 2024 Chevy Equinox, and I couldn’t be happier with the entire experience. My salesman, Jimmy Mack, was an absolute standout. Not only was he incredibly patient and deeply knowledgeable about every feature of the Equinox, but he also brought such a warm, upbeat energy to the process. Jimmy showed up in the cutest tennis shoes — and honestly, he put them to good use. He walked us through every detail, answered every question with confidence, and never once made us feel rushed. What really impressed me was how kind and respectful he was to my 80‑year‑old father, who can be a bit grumpy at times. Jimmy handled him with genuine care and patience, which meant a lot to me. I left feeling completely confident in my purchase and truly appreciated the professionalism and kindness shown throughout the entire visit. I would absolutely return to this dealership for future business and highly recommend Jimmy Mack to anyone looking for a smooth, friendly, and stress‑free car‑buying experience. More

We bought a car from Jimmy Mack / ELCO Chevrolet at the end of November. When I went to the DMV to register it, I was told the safety inspection hadn’t been completed, which was frustrating after spending end of November. When I went to the DMV to register it, I was told the safety inspection hadn’t been completed, which was frustrating after spending over two hours there. I called ELCO and Jimmy was quick to help—he got me in right away and the issue was resolved within 30–45 minutes. While it shouldn’t have happened, I really appreciate the responsiveness and effort to make it right. More
