I currently own a 2004 911 GT3 as a daily driver and want to make it a weekend car only.

My buddy has a 2004 M3 SMG for sale with 120,000 miles on it. The car has been maintained to spec. Anything I need to look out for? Should I avoid this car? Any info will be appreciated. TIA.

find out about the rear subframe, if its been reinforced. if not have that looked at. also find out if the vanos has been gone thru. last the smg, find out what has been done there. i have 6mt so not sure what is involved but those tend to need attention also.

check rear subframe for reinforcement, you will need it. See if SMG pump has been replaced. Ask about vanos. Most bushings will need replacement.
Have a PPI done.
buying a used BMW is the same as a used Porsche. Have someone more knowledgeable than you check it out.


Search the various forums. There are different ways to fix the subframe. SMG pump replacement is $1K or more. Vanos has the Beisan fix, which most say is the cheapest and most effective. Just due to age, all the rubber in the suspension needs refreshing. If this will be your DD, stock is good. If this is the new track toy, some people like going with polyurethane, AKG or powerflex.
I just bought a 2003 M3 and planning to turn it into a track toy. Track insurance for an 11 CS is too much.

For now thinking of using it as a DD, until it starts needing everything replaced. At that time I will turn it into strictly a track car. Gonna ask about the above mentioned. Thanks.
