I had a 1948 Cessna 140, It would cruise 105 MPH at 5.5 GPH. Mine had an electrical system, I think all 140's did, and a Cont. O-200. Great airplane to own and maintain. Insurance was getting expensive. I flew mine all over the country. Flew to many airstrips in the Idaho back country. I own a Cessna 170 now. Any airplane you get will hold it's value if you maintain it.
