You don't mention if you are a new pilot, instrument rated, etc. If a new pilot, do you plan to use the plane to build time and earn an Instrument ticket? Do you have time in retractable?
Point being, the purchase price of a plane is just the entry cost. The ongoing cost can approach the price of the plane in ten (10) years....maybe seven (7) years if you are new. And yes, paying more for a good, well-maintained plane can save you on yearly operating cost initially.
Have you budgeted for operating expense after the purchase? Maybe you are experienced and this is old news for you:
Are you going to put it in a hangar? Depending on where you are, that could run $200-600/month. Up to $7K per year
Insurance - Liability and Hull. If you are a new pilot, you might have trouble getting insurance at any cost. And if you are new and can get insurance, with a $136K hull value, I would not be surprised for you to pay up to $7K per year. There is a member here on MS that can assist you with getting insurance at the best price.
Even if you have some experience, you need to budget for some transition training - your insurance carrier will demand it
Annual and maintenance - easily $3K per year...likely more
The devil is in the details. For instance, you mention the plane that you are looking at has a GNS530W. Although a legacy GPS navigator it is still very capable. But when was the LCD panel last replaced? They do go bad and the Garmin flat rate for repair is now over $3K.
You will incur some annual expenses for flight apps/EFB and Jepp data base updates on your GPS box(es). That can add up - at least $500/yr.
And then there are consumables like avgas, oil and tires (if you are challenged at landing initially...)
60 hours @ 10 GPH = 600 gallons. Avgas prices are $5.92 nationwide and rising. That is another $3.6K per year
Even if you tie-down and are experienced, I doubt you can get your annual costs below $10k. And if new/low time with your plane in a hangar at a congested airport, you might be paying upwards to $20K annual expenses per year. And you need to keep some funds handy for the unexpected.
Aircraft ownership is a balancing act.
