My Civic had a shudder at high speeds, which had been there forever, it seemed. When I took it to Menlo Atherton Auto Repair, they had me take their mechanic Marco out to demonstrate the problem. That was the first time any shop had done this, and it made me think they would find the problem, which they did! So I'm a happy customer. They are very competent, and all around nice people. And, their hours are very convenient, 6am - 6pm weekdays, and even some hours on Saturday.
