My + batery cable corroded and severed. on 1999 Subaru Impreza Outback

I had the car towed to another nearby mechanic and the original quote multiplied 5x. they said entire battery cable harness needs to be replaced, not just the + cable. Does this sound reasonable?

another mechanic?? what happened to the first one??

the cables are special and the parts are not cheap. the bid sounds high by about 150-200.

I haven't told the 1st mechanic to do the work yet. $500+ just sounds high to me. Will get a 2nd opinion I guess.
yep, stay away from the dealer. they are always to the moon in price.
