Brake pads
If you are a DIY kind of guy then get the pads anywhere (particularly since you're selling it, what do you care) and then put them on yourself. You will need to get new sensors. I posted a DIY pictorial on the W210 here: https://mbworld.org/forums/e-class-w210/107227-okay-brake-job.html
Good luck and enjoy the ride,

If you decide to DIY and don't want to get the cheapest pads out there (yes, Autozone sells them - shudder) my favorite three online sellers in order are:
www.autohausaz.com
www.autopartswarehouse.com
http://parts.mbz.org
First two offer free shipping at the $50 price point, last one is at $75.
Take care and again, welcome.
