Lucerne CXS 4.6L V8

  • Automatic transmission
  • 34,798 miles

I found it hard to believe GM would place a battery under the back seat and not provide some sort of protection for the sheet metal floor under the battery. There is a drain hose attached the battery but it did not stop the acid from corroding a hole in the floor. Unbelievable for a car that cost $42 grand
