Other planes are CHT challenges 2) ease of inspection access - something easy to inspect will probably be caught earlier. 3) ease of maintenance - the same failure might be a 1 day downtime in one airplane but a 3 day downtime in another. I agree with your overall point. If you scatterplotted NA singles, pressurized pistons and turboprops on some maintenance axes, you'd have three discrete groups. But I could believe relevant differences exist between different models.

..and herein lies the underlying reason I'm not in a Mirage right now. It's a Piper, and not a Beech. I've reviewed the logbooks of late model Mirages for sale with 500-ish hrs TT and the parts that have been replaced already is very disconcerting. Not only cylinders. Lots and lots of cylinders. But heated windshields. Gear bushings. Complete PFD/MFD systems. Fuel pumps. On and on. Again, these are planes with 400-600 total time!! And what do you have to remove, like 200 screws, to get a look-see at the engine? I have been absolutely spoiled by Beech quality. After shelling out 5 or $600K for an 8 year old Mirage, I'd be mighty pissed to be putting $20-30K into it each year because something is always breaking. That would take all the fun out of plane ownership for me.

I forget where I got this spreadsheet from . . . But it seems to indicate quite a difference in UL between a 421B and a 421C. Is it accurate? Attachment: C421 Usefull compare.png

I appreciate all of the advice. I am going to look at a Malibu more carefully. Also does anyone know anything about the Extra 400?

Mirage is lycoming in an application it never loved. Malibu was continental engine. Malibu logs look much more like bonanza ones, especially when owners run the engines as designed (Malibu engine was designed from day 1 to be LOP, ROP ops were actually prohibited outside of climb in original logs)
It takes me 5 minutes to take top and bottom cowl off Malibu. What other piston engine takes less time than that?
The whole beech quality thing is baffling to me. Thicker skins and more rivets don't make less maintenance. What is beech doing that is so much better than piper of Cessna? The engines and avionics are where 90% of the squawks are coming from. I have yet to see any evidence that piper gear and flaps are any less reliable than beech or Cessna. Plus, talk to anyone that converts a Malibu to a jetprop. Squawks go to practically zero.

The A36 cowl opens up with a simple latch and gives you excellent access to everything top-side for pre-flight and most maintenance actions. I think it would be possible to tie it for ease of access, but basically impossible to beat (unless you literally didn't have a cowl at all).

Anthony, you're not seriously suggesting that Piper airframes are the equal to Beech are you? Now we certainly agree that late 80s Malibu's like yours with the Cont 550s are very desirable and the better option vs the Lycomings. Personally, if I were looking for a Malibu of that vintage, I would only consider one with the 550. However, my interest lies in a later model Mirage with a low time engine. Like I said, the mtce I see in the airframe and engine logbooks of 8-10 year old planes with well under 1000 hours is disturbing. But hey, I'm a realist and look at it tis way. It is what it is, and if I'm not willing to deal with it, then I shouldn't buy one. My search is just beginning to intensify so we'll see where I end up. I may come to realize the wisdom of your advice and try to find a well maintained Malibu with a low time 550 and full glass upgrade.

We are a family of 4 with a 16 yr old boy and a 9 yr old girl. Without question, when the 58P is ready, the utility with it is going to be much better than the A36. By a wide margin. My payload is going up by at least 300 lbs and my luggage will be in the nose. We often fly a 2hr 330m trip to the beach house and soon will be flying around the south following a college baseball team (yet to be determined which one) and the numbers say we can take a set of grandparents to the games in the 58P and have no payload left in the A36 for them Note: oldest kid won't be in plane for game trips, he will be on a bus haha I just have to get it ready to go in the next 18 months

Robert, you have a heavy A36. When you have a 1300+ lb UL in an A36, the advantage of the 58 is not in the weight carrying ability, it's in the ability to load the baggage in the nose, By way of example on the loading:
Let's assume you carry 3 hrs of fuel for your trip. Let's use your 58P's 1845 vs my UL of 1325 as starting point.
I could carry 40 gal of fuel for the trip, with a full hour reserve, leaving me with 1085 net.
Same 3 hrs fuel load for you is closer to, what, 135-150 gal? Let's go with the 135 gal figure. 810# for fuel leaves 1035 # net.
Slight advantage to the 36. But big disadvantage in where to put the baggage. Not so much of an issue for you in the 58.
