Side steps look good, but a waste of effort.
Hard to use to get in and out. On uneven ground you have to step out further to get foothold - would be ok if you had a ‘go go gadget’ leg that was telescopic !!!
Trousers get wet, yes you can wash front half of roof easier, useless to wash rear half of roof.
Looking to remove from my wagon.
Wife has GLC Coupe and we deleted them on build state - best decision, much easier to get in and out.
I use a small plastic 2 step stool to clean both roofs, purchased from auto shop. Safer and easier.
