I went through this process and bought a 550i wagon a month or two back. There is a thread down the page somewhere. Yes the lci came in 2007, which has among other things the electric transmission shifter (meant to be very slight better for fuel use), led taillights and other cosmetic mods. Definetly get the motorsport version. The V8 I have found on open road to be pretty good on fuel maybe 12l/100 and round town obviously worse, wouldnt be much/ if any more than my old ba xr6 falcon. Any other questions fire away, I think its a great car for the money.
