My '02 Buick runs perfectly due to regular maintenance performed by Portland Automotive. It is always checked out for any problems that might be there and I am advised beforehand for approval to do any necessary repairs. Coupons are mailed periodically and they do save a few dollars but you MUST remember to bring them in for the savings when the car is being worked on. The staff are very pleasant and accommodating. The big plus is being able to use their courtesy car when needed. Thanks....
