If it is me, please let me know...
I took someone's plane up for a test flight and it didn't go super smooth. I asked if I could go up another day as I wasn't positive it is was me or the plane. The second flight was quite short, and it solidified that there were some things about the plane I didn't like, so I was no longer interested.
During those flights, I offered to and did pay for gas. In all for both is was 1.2 hours of flying.
I sent him a very nice email saying thanks but no thanks. He writes back and asks for $120 for the time flying the plane. This is over twice the rate the guys use as their maintenance reserve rate ($100 an hr vs $50 an hr quoted as part of group ownership if I joined). He'd never mentioned anything about me needing to pay for a maintenance reserve, and I thought it would be appropriate to pay for any gas I had used.
What do you guys usually pay for when trying out a plane to buy? In my mind, those are costs of selling that should be the responsibility of the guy selling his share. I've sold cars and motorcycles and never asked for money for their time in the car for maintenance expenses...
On the plus side, I now know I made the right choice not entering that partnership.
