Unbelievable..!

[mam4.6]

So, my wife and I picked up the X at our mechanics yesterday, my wife drove it an hour and a half b4 we got home. She mentioned something about a shimmy in the steering, I thot I'd look at it today. WELL, today, I drove it a bit, shimmy seemed to be getting worse and worse, so I crawled underneath, thot something mite be scraping somewhere, as I heard a grinding noise from the front end. Then I looked at the wheel itself, and nearly fell over!!! There was only one lug nut loosely threaded into the wheel, the other four were nowhere to be seen! I immediately called him up, he dropped everything, came to my place and tightened everthing up, and check all the rest of the wheels as well. He was absolutely mortified, and said I will get a brand new vanos install free of charge or labor, if I want to come back to him So, should I trust him? He did excellent work on everything else, so I kinda like him....
