Concur with Roscoe. Scott E. from FletchAir did my pre-buy and it was very thorough.
Common things I wish I would have picked up while there:
– New Nav light lenses
– Stickers! My airplane was missing all the Grumman stickers, they have some, but not all.
– New placards (if any of yours need replaced)
– Interior Plastics & Windows (if you need them). Costly to ship!
Oh, and I hear they LOVE it when you bring them BBQ. 🙂
