"Great shop I highly recommend taking all of your vehicles here! Everything shines, from the massive shop toolbox to the floors you could eat a steak off of. Amazing upkeep and quality in everything they do. Not to mention the awesome staff. Jack a technician at Long Hill Auto gave me a bag of tea that made my night. I have to say... Jack is the best... 5/5 10/10 100% A+ Service."
"Long Hill Auto is BY FAR the best car repair experience I've ever had- and I've had MANY. First off, when you walk in the shop office, it is set up like a dealership. Bob has key chains, magnets, coffee, tire pressure valves and even customized "Long Hill Auto" water bottles. I've never seen a more professional repair shop in my life. When I had to use the bathroom, I was expecting to walk into a grease covered, disgusting bathroom, which is standard for most auto shops. I was floored when I opened the bathroom door to a bathroom cleaner than mine at home. It looked as if it was regularly cleaned, and there was no dirt, oil, or grease to be found. the soap provided was ocean breeze, not mechanic hand soap. But of course, this type of cleanliness is indicative of the entire shop. The office, the outside, even the spaces by the lifts where the mechanics work on cars- immaculate. For this specific issue (lean code), I took my car to two different mechanics who both worked on my car for weeks and couldn't fix the problem. Long Hill diagnosed the issue within 20 minutes of me being there, and fixed it within the week. I got my car back WASHED AND VACUUMED as well as with AIR in all 4 of my tires. During the few days I didn't have my car, I was given a LUXURY loaner car. The Infiniti Long Hill provided me had Sirius satellite radio, leather seats, and oak wood interior. I've never heard of a repair shop giving their customers a loaner car in general, let alone a fully loaded luxury sedan!! This shop is the classiest act going! You will not find an Owner like Bob who takes more pride in his business and his work. As if the incredible service wasn't enough, the prices for all work done were fair and reasonable. Save your money at the dealership and take your car or truck somewhere much better, Long Hill. I will not be taking my car anywhere else ever again. From regular maintenance, to pesky issues, Bob and the team at Long Hill will always have my business for as long as I'm driving!"
"Great service! Emergency car problem solved! Saved my day! My go to shop for everything from now on."
"Long Hill Auto Service reminds me of what was once synonymous with service providers - customer focused, knowledgeable and quality. I found myself a new mechanic and would highly recommend Long Hill Auto Service."
"Awesome service! Had our BMW towed from highway and was back on the road fast.. friendly and welcoming guys!"
