i changed the grill to oem but its painted black

 

Always ask for more so when ppl try to bargain you still get what you want. If its 24K your looking for really then price at 30K and let the buyer feel like he won by getting it for 5-6K less than you posted it for. That way they feel like they got a deal and you get close if not exactly what you planned on getting.

 

But don't put it too ridiculously high or people won't even bothering throwing you an offer

 

Always include Or Best Offer of course.

 

man i dont even think i want to sell it anymore! i raced my buddy with a 2008 6mt M3 and beat him coupe times and kept up with him the other times

 

I wouldn't sell it... if you absolutely must get a new car try and part out some of the mods, you've got a decent list going you'll lose so much money trying to sell as is its ridiculous. If I ever decide to go with a new car I'm ripping everything out of my coupe, throwing in a $1800 junkyard motor and selling it as close to stock as I can get.
