Yeah bro... if the car doesn't start up right away, 7k is a lot. I'm going to play the part of "devils advocate prospective buyer" so don't think I'm being an ass.... your kbb value is around 4,600 private party value. Why should I buy your car if it doesn't start up properly. I could probably find other modded z28's out there for less than what you are asking that start right.
If I were you, I'd definitely fix the starter issue- only then can you really justify starting to command more than kbb price, unless you parted the car out and sold the aftermarkets separate from the car and just sold the car for kbb.
But good luck bro, keep us posted.
