I'm relearning this lesson again trying to sell my MIM Strat. While most MIMs go in the $300-350 range bone-stock, I've tried to sell mine with a good $300 worth of upgrades for only a little bit more then the normal used price, and if I get another nibble it will be the first one. It doesn't matter the real worth of the guitar, only the perceived worth.
I imagine if you saw a Daytona with all the upgrades you're about to do for the price you're about to pay to have them done, you wouldn't pay that price. "What? $1200 for a Daytona? No friggin' way!"
