It's worth about $45.00 and I'll be over next week to pick it up. I can give you a $10 retainer fee to hold it till then.
I'm only kidding. Hard tops generally sell between $500 and $1500 depending on the condition, features, and year. Just a plain hard top in good condition off of an 05.... meh, maybe $900-$1100 depending on the local area.
