Hi Tim;
My name is Steve; I’m the person on staff that works to answer technical questions.
I did look over the TAP ad in the link you sent. It’s pretty impressive as far as modern equipment. It seems to me to check every box in the modern avionics and airframe pre purchase checklists.
I can’t comment on what it’s worth except to say that something is worth what someone will pay for it. In my experience over the last two decades of working with pilots buying airplanes is to buy the best airplane you can afford. Let the guy/gal that dumped a load of money into the upgrades/improvements take the loss because the value of an upgrade or modification is never recaptured when the airplane is sold.
I suggest you click in the “magazine” tab at the top of our forum page; a drop down menu will list articles and back issues of the magazine you are free to access.
Here’s a link to one of the pre purchase articles:

In order to make sure you’re getting what’s advertised you should establish and escrow acct and do all the financial maneuvering through it. If you’re serious tell the owner you want to pay for a in depth pre purchase survey. He may require some earnest money; make sure it’s included as part of the purchase funds should you decide to buy.
I also recommend, due to the avionics suite that’s installed to hire an avionics expert to check out the avionics to determine if everything is working correctly.
The first step in an airplane purchase is to define your mission–the flight length, load, people, etc. you will take most often. Do you really need retractable landing gear, etc. I realized after buying my 3rd airplane that I needed an airplane that is comfortable, economical in the speed/cost ratio, and well supported.
I had owned a Piper PA 12 taildragger and a Cessna 182. One was slow and had limited load carrying ability; the other had more load carrying than I needed coupled with a relatively thirsty engine in the speed/cost ratio. The airplane that I’ve had the last 17 years is a Piper Comanche. It has a 180 hp engine, retractable LG and a CS prop. I consider it a two place airplane for any longish trip. It has worked out fine for me.
What is your typical mission??
Please get back to me with your answer
Steve
