looking to rent instrument cluster removal tool for 01 W210.

Buy it, they are very cheap. eBay is a great source.

Or cheaper yet, make your own. It's just a thin metal rod bent 90 degrees at the end. A coat hanger will work fine.

I use a paint can opener on my W126. Since it is flat, it does not damage the dashboard and it was free from Home 'r' Depot...
