I had an absolutely amazing experience working with Gene while buying my car. From start to finish, he was friendly, knowledgeable, and completely transparent. Gene took the time to really understand what I was looking for and didn’t pressure me into anything. He answered all my questions with patience and made the entire process smooth and stress-free.

What stood out the most was his honesty and dedication to making sure I got a great deal that fit my needs and budget. He truly went above and beyond, and you can tell he genuinely cares about his customers—not just the sale.

If you’re looking for someone trustworthy, professional, and easy to work with, Gene is your guy. I’m beyond happy with my new car, and I’ll definitely be recommending him to friends and family. Thanks again, Gene!

DO NOT BUY FROM MAINLINE AUTO- A friend of mine who only speaks Spanish purchased a used Honda CRV from Mainline Auto just two weeks ago, and it has been nothing but a nightmare. Right after buying it started experiencing major issues, including:
Collision System Malfunction
Electric Parking Brake Problem
All-Wheel Drive Indicator Light
Brake System Hold Malfunction
Power Steering Issues
My friend ask me to contact Mainline Auto for help. I was met with complete indifference. The salesman who sold the car Tony outright told me he was "too busy for this" and hung up on me! That alone speaks volumes about the kind of business they run. Instead of standing behind their sales, they abandon customers the moment they drive off the lot.
If you're considering buying from them, DON'T. They sell cars with serious problems and refuse to take any responsibility. A reputable dealership should care about their customers, but Mainline Auto clearly does not. Save yourself the stress, frustration, and financial loss—go somewhere that values honesty and customer service.

the staff in this dealership is the best staff I ever came across they go above And beyond with the customer service  from the salesman to the person that does registrations are awesome. real quick and easy and they make Sure that your vehicle is at the tip top shape. It can be when you purchase it. I recommend everybody to go here

Excellent service at Main Line Auto Philadelphia. They treat you like family no matter where you're from. Manuel-Manny treated me in the best possible way. He has a lot of experience and I’m driving off the lot with my new beautiful 2023 Jeep Cherokee.

I had an amazing experience at MainLine Auto! After months without a car, Manny helped me get back on the road—and I couldn’t be more excited! He was patient, knowledgeable, and made the whole process smooth and stress-free. If you’re looking for great service and a team that truly cares, I highly recommend stopping by and asking for Manny!
