You all have to be dreamers or kidding!
1. You haven't flown for 6 years
2. You have only had the 182 for a couple of months and only done 20 hours
To assess the impact of an aeroplane on your business you will have to have owned one for at least a couple of years. Without being pessimistic, you will be lucky to recoup your 130K if the engine is timex, IMHO half of that would be optimistic. Selling it for more than this could take loads of time, perhaps put it on the market and see.
Keep the 182 (unless someone will give you your money back) and concentrate on getting the business really cashed up, AG is booming at the minute but the global economy seems fragile and having a cashed up business is good sense! Get some real hours under your belt and live with what you
have! A 182 is a very capable ship. Try not to spend money on it unless you have money to burn.
