The eBay listing has a "Make an Offer" feature. I'm fairly certain you already know this, but an asking price is just that...an ASKING PRICE. My starting point is around the midway of the three most recent listings I've seen (mine included) - even though it's in the best shape of the three.
Maybe you don't think you're trashing/undermining, but I doubt you'd appreciate someone swooping in on one of your posts and hijacking it with comments about old prices that are way under the current market value, alternative non-OEM parts from other suppliers, and anecdotes about other people's strut bars breaking in half. At this point, you're making comments that are actively discouraging people ("I would hate to be the guy who pays your price only to have this part break in half 6 months later...").
I'm not trying to rip anyone off, so nobody needs your protection here. I'd appreciate it if you'd stop. Thanks.
