I've flown 172's that have barely more than 100 hours on them, and I've flown 152/172's that looked worse than a Yugo run through an acid car wash. Sure the newer planes are nice, and have all the fun stuff, but the older ones get off the ground just as easy (usually

) and fly pretty much the same. My advice: Fly the older planes and use the money you saved to get more X/C time.
