sorry to jump in so late, but the 2nd pic says mercedes 5.5L AMG??
that speedometer is from a W21 e-class from before 1999 (meaning 98 and back) and this meter only came in the E36 and E50, the E50 had a different display at the bottom.
also the E55 is a 5.4L not a 5.5L.
sorry but i think you are lying.
