$113, actually. My drive shaft bearings had gone bad, which caused the smoking & grinding. My beloved Volvo is saved from the knackers again.
One reason she is my beloved is that she actually has RUBBER BUMPERS. This means if I hit something gently, or someone bumps into me, there is bouncing, not the expensive crushing of plastic. This is a pet peeve of mine, that all new cars have nothing but plastic molded frames that cost a ton to replace - there is no repairing.
Anyway, all's well that end's well. Now we just have to hope that we have no more towing incidents until our AAA renews - this was our last free tow.
