retractable undercarriage on older cessna's req. a good crowd to do all your servicing. If you go for a 210 make sure you avoid the gear doors. Heard some stories about those things, not worth it for the extra performance. I fly a turbo 182 and it burns 15gph + @ 10,000ft so if you are getting 13gph out of a 310hp aircraft then I thing your cooking it mate!
