I have a 90 300zx with 73k on it, KBB private value is $5760 excellent condition all options. I know kbb is bs to Z owners, but I then looked up my moms friends 90 300zx with 250k on it good condition not all options= $3470. My fully loaded Z with 73k in excellent condition is worth $2100 more than a good condition with some options 250k mile Z. I guess what I learned is I can rack up the miles and not lose too much value. I wouldn't use KBB anyways and dont plan on selling my Z anytime soon though, but she is was selling hers and wanted to know the value, that sucked to find out.
Follow Ups
I feel hurt, but I found this interesting about mileage.. - sleepy-z14:12:42 08/27/05
