1998 BMW M3 Sedan 4dr Sedan
Best Overall Sports Car Ever
 I have had my 4 door M3 since 2003. I bought it from a private dealership with only 17K miles on it.  I added the Dinan software one day at the dealership on a whim and wow 155 mph and I had to stop. It might have done 160, but who knows, I could also have gone to jail because of that. Used it as a daily drive until 2007. Now it is strictly for weekends and appointments. I have a truck for daily use now.  Now have 107K miles. Normal maintenance and no major problems thus far. I could keep this car forever. My 9 year old son loves it and wants me to keep it for him when he gets 16. Yeah right!
