I am interested in buying a used M3, but am unsure if I should go with a 1995 or a 1996 model. The 1995 model is the last model to use the OBDI, while the 1996 model used the OBDII. I am interested in modding it, so this is why the OBD version concerns me.

Also, some of the cars I am looking at have almost 100k miles on them. What is the given life of the engine, and how reliable are they? BMW parts are expensive, but I have heard that they are reliable, excpet for a few cases. What are your guys' experiences in maintenance and performance?

As for the modding, do you guys have any companies you can recommend to me for chipping? I heard Dinan was pretty good, but I'm just looking for different opinions.

Thanks for any help =)

Hey man, you need to check us on Bimmerforums. We have all the answers! :)

OBDI is the course for you, if the age of the vehicle does not cause concern.

Some companies for software mods are Dinan, Active Autowerke, Turner Motosports.
