I'm also a car guy and love Flows
I'm also "cash is king" I never take trade unless it's actually something I want for myself. Not to say this but you can get burned especially when it's something you don't know much about or in hopes of making the money back.
Unfortunately to move them this time of year I think your looking at $150 ish if you get real lucky $175
Do you care to share with us what parts you traded?
What car you drive that your slammed?
I just installed CO's on my sons GTI this last weekend and that is as low as I'll let him go and damn that is to low for my liking.
Again good luck on the sale.
I traded a carbon fiber e36 m3 ltw that I bought of Craigslist that needed a refinish. I currently have a Mazda 3 that's slammed. My dad is the same way haha
