You had one job!
I think you are going to scare away some people calling it a weekend/ track car. I had the same mods and a few more with full suspension on my 07 and it was my daily driver for several years like that. Also saying she is loud will scare them away.

Not sure how prices are in your area but asking 18K would be pretty high here with 124K miles. I sold my 07 in 2013 with 64K miles for 17k.
