Not sure if the feedback section is the right place but after 20+ years of knowing Jim and the work he does I finally had the privilege of sending my car to him. He installed a ton of parts I sent and even had the AC checked and converted to R134. The entire process was communicative, incredibly thorough, and the end result was a completely refreshed Buick with a LOT more power and the comfort to drive around with cold AC in 80* heat while the car didn’t go over 167*. If you are on the east coast, or just want to make the trip to this top-notch experienced Buick specialist, I cannot recommend him enough. His knowledge and attention to detail are things you rarely find nowadays. Thank you, Jim.
