Check Engine Light On - P0130 Code

So I posted in the w203 forum and no one answered, so hopefully you guys will help more.

I had my CEL ON after a very "aggresive" acceleration .. (ptffff) I cleared the code and came back again, same code so I assume it is indeed the O2 sensor (ODBII Code: P0130, bank 1 sensor 1), I called my stealership and cordially asked him to quote me the price for the O2 sensor, gave him my VIN and he said "which one? the front or the back?" I was like whaaaaaa? I didn't know the sucker had two, which is not a big deal if the price wasn't twice as much!!!!!!!! the front one is $139, the back one is $390!!! Any of you experts know is p0130 is the front or the back one (I am just hoping is the front one!, wherever that is)?

Thanks

BTW, I drive a c230k coupe '02

Bank 1 is the cylinder bank that has the #1 cylinder. Sensor 1 is the O2 sensor that is before the catalytic converter. The reason why the prices are different is because the sensor before the cat is used to adjust the air/fuel mixture (simpler function), and the sensor after the cat is used to monitor the cat's performance (complex function).
