alex is a great guy, he did all those mods to my 2007 X5 4.8 and everything works great. hes knows his stuff and does it in no time. the x5 looks alot nicer without the turn signal lights on all the time. the folding mirrors are cool too. and the best part is the windows finally go up with the lock button. makes no sense as to why the would go down with the unlock button but they dont go up unless alex programs it. the m3 speedo is a nice feature to. send him a mesage and he'll take care of you. he knows his stuff. im sure you wont be disapointed
