Hello! I just bought my first M5 a few months back. It is a CPO 2013. I took some time to do some mods and this forum has been awesome for inspiration! This forum also helped me find some parts! Anyways, I thought I would share what I've done to the car so far. I hope I'm worthy of a post here!!
Mods so far:
-RKP Front Lip
-IND LCI Cosmetic Package (Black grills, Painted reflectors, Black emblem)
-CF Exhaust tips
-H&R Springs
-H&R 12mm spacers in the back
-HRE S101 21" Black Satin rims
-Diono car seats
Haven't done any motor work yet but not sure if I'll do too much. As you can see this is a daddy car with two car seats in the back for my girls. Best family car ever!!
Thanks for looking!
