The first pic looks like middle of summer, the car has probably been for sale a while.

I'd be asking for the vin to verify it is a E55 , of they don't want to do that, the first 2/3 might show if AMG.

The trunk is dented (left of plate )

The title of the ad and listing show no effort to sell.

If the car is a rusty mess, find a clean shell and convert.
