unfortunately they no longer make Buick car parts, you should take your vehicle to the local junk yard and get as much cash as you can for it.

Fixed mine myself. Just bought car and needed milage for title. So easy to do. 4 resistors over heat after years and come unsoldered. Check youtube with search " Fixing ODOMETER on 1999 Buick. Took me about 30 minutes with no need for special tools, but you will need soldering iron.
It was $150 at the dealership where I bought the car. $240 to replace it with tax and labor.
call your local dealer
A Bosch O2 sensor, from NAPA, is $91 here in southwest Washington.
Between $40 - $60 seems typical. The actual cost will depend on specifics of your vehicle, such as which engine it has.
It's in the middle of the dash on top. Not sure yet how to remove it, just checked with the parts dept at a buick dealer. Cost approx $62.00 part only.
