I've been here a couple of times before they moved and once at the new location.Their prices seem fair, and they always seem polite and honest.This last time, I had rear brakes and rotors replaced and a driver window repaired for my wife's van. Total for parts and labor was about 600 each (~1150 total).

Brought my car in for what should have been a steering rack bushing replacement. After a short assesment they determine my rack & pinion was damaged. Instead of doing a repair that would not have fixed the problem they showed me the issues, with pictures, explained the repairs I actually needed.Hats off to an honest business who did me right. I'd be thriled to continue future business with them.Paul was my point of contact, was great as a person and a salesman.

We have started using Lens in the last few years after switching from another mechanic that was too booked. It is easy to schedule, get service & pay every time! Michael is always taking great care of us. We have been nothing but happy with the work they have received.

I've been using Len's for nearly a decade now, and I couldn't recommend them more. Great customer service, very knowledgeable staff, reasonable pricing. They won't try to upsell you or pull a fast one on you, just an honest, local mechanic that does great work. Five Stars.

I dropped my car off at Lens for multiple repairs / general maintenance, at substantial cost. After one full week of delays and spotty communication, I finally received notification the service work was complete and my car was ready for pick up. Upon payment and receipt of the vehicle, it was immediately clear 2 of the repairs I paid for were not completed. I immediately returned to Lens to inquire, where I was informed that no one bothered to verify the repair work actually fixed the issues (no quality control). I subsequently spoke to the co-owner to provide feedback. He was largely indifferent. While he mentioned there was opportunity to have done things differently, he offered no apology for the sloppy mis-managed repair work, and was not interested in making things right. He basically stated Lens would be happy to complete the 2 failed repairs at significant additional time and cost to me. Be wise, do not waste your time or money at Lens. They are a “volume” shop focused only on how much money they can generate, with little (or no) emphasis on quality and customer service. There are many better repair shops in town that are much more professional, competent, and value the business and loyalty of a good customer.

Excellent customer service. There are industry wide delays. I checked by calling around. Todd was up front and honest. I went in for a transmission that was done in a very timely manor. Yes there was a delay on the transmission but it was out of Lens control. Then Lens kept on top if it to make sure they could get my van back to me asap. Todd knew I had a baby coming and felt the brakes a little loose and offered to fix them before the baby is due. He knows I can change brakes and calipers but also knew I probably wouldn't want to do it because my baby is due in a week. I know the vehicle could use an alignment and some other easy maintenance items. Todd never brought it up. Any decent mechanic felt the slight pull to the right while they while driving the vehicle around. The vehicle is due for inspection in a few months. Todd knows I'll be back because I honestly trust the heck out of those guys. He also knows that I'm probably a bit overwhelmed at what I just spent there and stressed with a new baby on the way. That alignment can wait and we both know it. He never even tried to tell me. This is customer service and knowing when to let something minor go. He doesn't know how much I know about vehicles excpet I can probablychange the oil and do brakes. Lens treats my wife (who knows nothing about cars) the same way they treat me. They let us know what the car needs and what the car could use. They know what can wait and what should probably be done soon. Could not be happier.Btw, I could have pulled that transmission and done it myself (Dad was a mechanic), but it's a pain to do it so I sent it in. Great job.

I was in the area visiting family when my van started having power issues at stop lights. Since it was the 4th of July, the best I could do was run a test at one of the auto parts stores. The report came back that it was a starter or alternator problem. I didn’t want to risk driving back to Pennsylvania without getting it fixed. I was nervous about finding a mechanic to trust and who would fit me in with no notice. I called Len’s first thing in the morning and he told me to bring it in right away. He said they would slip me into the schedule. I didn’t have much time because we had to leave the next day. I told them I thought it was the alternator. Three hours later they called and told me it was all set and ready to go. I asked what was wrong and they told me my battery cables were loose. They didn’t charge me for the diagnostics or their time. Instead, Paul sent me off with a good luck and wished me a safe trip home. I’m so grateful for their friendly and HONEST service. They could have sold me a new alternator and I would not have been the wiser. The folks at Len’s were perfect. This would be my “go to” place if I lived here. Thank you!!
