BMW M550d (LPAN) - BERLIN RENT
Sixt says:
class: LPAN
MODEL: Premium class e.g. BMW M550d Limousine/Touring *NAVI* or similar.
Does anyone know what is similar to that? What other car may I get? Is it possible as platinum an upgrade to a superior class(m3/m4,etc) complimentary ? Any idea how much a paid upgrade to a m3/m4/m5/mb amg would cost?
