Hi my name is Adrian. I am from Poland and I'm a new owner of e39 M5. I bought it at the IAAI auction from Florida. In my opinion this is Dinan s1 version plus upgrade .This E39 M5 also has a Vortech V3 Supercharger, koni suspension, stoptech Brake calipers and rotors,dinan exaust, dinan strut bar. I found a movie from the 2015rand also I wrote to usmdi.com to ask about car history, but unfortunately they didn't answer. Is there someone who can Tell Me something about this car? Know maybe history or have some informations about previous Owners?
