Buy a WRECKED M3 or really cheap one.
Be brave! Just buy a wrecked M3 at Salvage like I did.
There is No Fear about screwing something up and I have learned more about the M3 in two weeks than I ever knew about my M Roadster because I was always afraid to work on it myself. NO MORE BABY.
I will be looking for input from this group as I bring the Phoenix from the ashes to the Track.
