Called Tim's Automotive in Clackamas, Oregon for Oregon DEQ testing of my 2004 Tahoe. Spoke to a courteous receptionist, who put me in touch with their Service Rep. Though an auto repair shop, the property was clean, well organized, and inviting. Nearly twenty years previously, a previous employer of mine, located on the same street, utilized this repair shop, and to this day, their great service continues. I certainly would recommend to family, friend or acquaintance.
