Go with the Saratoga and find a new instructor. I bought a 1969 piper arrow, a single engine retract, complex, hi perf. Aircraft, and took my first lesson in it on the flight home. Everyone said start in a 150, then go to a 172, then in a couple of years, move up. I thought that was hogwash. I was going to fly several hundred miles very often…and I wanted a plane that would do it comfortably…and faster than a 150. The retract was a handful as a student pilot, and the insurance company required me to have 15 hrs before solo. I never looked back. I trained in MY plane, the plane that I flew most every weekend. I kept that plane ten years, flew well over a hundred hours a year…and got my ifr ticket in it. 15 yrs ago, I sold the little arrow, a solid 140 knot aircraft, and a great ifr platform aircraft, and moved up to a twin Cessna .
I love the Saratoga…find a new instructor…build some time, get him/her to go with you on some of your long cross country’s, be safe, get your ifr ticket…it will make you a much better pilot. Have fun!
