Matt and Kyle saved me well over $400! I had an engine light which gave a code of P0300 "to many…read moremisfires". The code recommended me to replace plugs, wires, vacuum leaks and various other crap. Matt said, "I'd love to take more of you're money but let's start with the exhaust. Take it to a exhaust shop and have them leak test it. Then come back, see me and we'll go from there." Being new to Derry, I had no clue where to find an exhaust company locally so Kyle and Matt both recommended Lou's Custom Exhaust. Boy they were on point with the issue and how to fix it...and they were absolutely right! I have no check engine light now! Thank you both for your knowledge and assistance.

The other review is spot on. I've been doing business with Sanel's SAS since the 70's! Now that…read moreNAPA bought them out they lack many of the little items SAS carried and have to wonder how stocked the Heavy Duty side is, and the prices have gone through the roof!

These guys recently transitioned to NAPA auto parts. This happened in January '19. Unfortunately…read morethe old Sanels was TOP NOTCH due to the sales people having dealt with the old product lines for years and knowing the software systems they use inside and out. Now that it is NAPA we have new product lines, the prices have gone through the roof, completely different software, and changes in how management over sees the stores. I have been doing business for years with Sanels, won't be doing business with the new Sanels NAPA.

This person (not sure if it was the owner I would assume so) is crazy!!

He then started threatening to have me arrested for trespassing Wow!! Good businessmen. People he does towing and salvage I would not recommend this company to anyone. This person is a hot head !!

On the way to get cash for it (he doesn't accept cards), I called another salvage yard who said that they didn't have the part, but would usually charge $35 for it. When I asked the owner of Watt's why his price was higher he became extremely belligerent, yelling about how his offer was non-negotiable and if I didn't like it I shouldn't let the door hit my (rear) on the way out. After berating me for several minutes I tried to play peacemaker, even going so far as to apologize if my question had offended him, that wasn't my intent. He then proceeded to yell and curse at me for several more minutes. I might have considered paying his price, but had completely lost interest because I was so disgusted with the way he treated me - a fact I informed him of as I left. Insulting your customers is certainly a unique business strategy, but not a particularly effective one. Terrible.

You also left out that I was offering to leave the bike on Sunday for you to work on it during the week. Your light staff on Sunday? You had a person there for a $25.00 sticker and treated me like I was a bother trying to continue to do business with you. The only person missing from your staff that day was the finance guy. Otherwise, it's always been you, the two older folks, and sometimes the finance guy. You state in your response you had no issue with continuing the business relationship but, are you not the one who handed me the tire and said to go elsewhere?
