bought the car: The clanking noise got my attention and when I took off the center "cap" of my wheel, 3 of the 5 lugs were conferencing at the bottom... they had sheared off due to ??? (too tight or too loose?) Anyway the worst actual result (not the potential !!) was that the holes in the wheel of the two remaining were ovalled to the extent that no garage would put a tire back on the wheel.. I ended up repairing the wheel, as it was about $400 to replace. Pretty scary...
