That Caddie has the high-compression 472 motor, which needs a higher octane gas than is available at the retail pump, in order to run properly -- check the owner's manual, but am guessing it requires a fuel of at least 98 octane to run without pinging.
Are you sure that it has 5K miles, and not 105K miles? The odometer in that car does not register and show the "hundred-thousands" number, such as found in the newer cars.
Check with Edmunds.com, or KBB.com, or poke around on Google and find one of the national Cadillac club chat boards that can give you further guidance.
