Had regular service on vehicle as recommended by owners manuel. Also, numerous other repairs, as needed, ( by service department). Outrageous charges for parts and labor of $3032.00. This vehicle is a 2012 with 38,500 miles. I would classify it as bordering on a lemon!

Always polite and friendly . The service department appointments are on time. They don?t pressure you into repairs that don?t really need to be done like other dealers.

Weirs Motor Sales
My vehicle was in for an Oil Change, Air Filter replacement, and new tires. The service dept ran into an issue getting my vehicle to align properly after multiple attempts with different technicians. Know that I was waiting at the location for my vehicle the Service Manager informed me of the issue and what was done to correct it to that point. He offered me the option of dropping off my vehicle a different day so they could get the issue taken care of. He also gave me a vehicle to use while my vehicle was being repaired as well as matching the tire price and even found a rebate on the tires I purchased. I purchased my vehicle at this location and would recommend Weirs Motor Sales in Arundel Maine to anyone looking for a GMC vehicle.

Great experience--Thanks Ryan McGuire!
I bought a used 2015 CX-5 in 2015 from Seacoast. From start to finish, the buying process was great. Absolutely no high-pressure sales tactics. No tricks or gimmicks. I got a fair price for my trade. And a good price on the CX-5. Salesman Ryan McGuire was patient and knowledgeable. The service dept was also top-notch. They took care of a bug in the entertainment system right away and made sure the car was perfect before handing me the keys. I would highly recommend Seacoast Mazda.
