Hi i just bought a 94 c230 and i have a couple questions about it. Does it have a supercharger? And what is it going to cost me to change the oil for example on this car? Do i have to go to the special place or just any oil changing places?

And also the 2 driver side doors been replaced and the wires werent connected, so i cant adjust the seat oropen the window on both doors,would i be able to connect it myself?

Thank you for help
