I've just sold my aztec after 5 faithful years. They will carry six adults , luggage and fuel, TAS at 160 kts, and have great single engine performance and asymetrics. They are pretty much bullet proof, and a great introduction to twin flying, as well as being a stable twin IFR platform. You won't have to part with big money to get into one.
The A-d models don't have twin hydrolics, but most have had added later, the E and F's have as standard. They also are great short field performers.
They will climb on one engine, ( if you have at 4800 lbs ie wife two young kinds and 450l , you'll climb at 600 fpm on one engine)
Senecas are a lighter aeroplane 2000kg verses 2300 kg , the seneca 1 is no go ( non turbo) the 2 is OK ( turbo) while the 3 is better again ( more powerful turbo).
