Take a look at the 177B or RG instead
I own a 76 Cardinal 177B and have a friend that just sold his T210N a few months ago. It took a long time to sell. He sold it because of the fuel costs , maintenance fees and the fact he was spending about $10,000 per year (on a good year) to keep his plane in an airworthy state. Routinely saw $5000 annuals when there was nothing extra to be done.... which was rare. His first annual after purchase, with a descent pre purchase inspection was $27,000. He envied my cardinal even though it flys at 140 kts instead of 165 kts.
