Had My '97 ETC hauled 900 miles to Midwest Cadillac Repair. Took Joe less than a week to do the head job using NS Performance studs. Also did rear brakes, tune up, new dog bones, tranny service, fixed my wipers, trunk and fuel door buttons, new fuel pump, alignment and tire rotation, even picked me up at O'Hare. All for less than 3 large. (not including the transport or the stud kit which I purchased separately) Drove it back home 900 miles. No problems. Runs like bran-new. Great guy, great service. Worth every penny. I won't hesitate to take my STS to him as well, once it gets a little miley. For any Northstar car that is in otherwise good shape, this is a no-brainer.
