I got my car back from a shop once, heard a funny noise from the front. I took off my front left wheel and found out one of the bolts to the strut was VERY loose. I sat back in disbelief for about a minute...then proceeded to check every bolt on the car that they had contact with. I found another one that was stripped and loose. Scared the hell out of me.
Yeah, so definitely do your rounds of investigation before driving a whole lot...
