Why do you think I have a Dealer account with Spruce . . Lol?

It's a long story. It was partially disassembled when he bought it from the estate. He has been persistent, to say the least, in getting this airplane back in the air.

The best $4 you will ever spend on a Mooney is this: https://www.aircraftspruce.com/catalog/cspages/warningonlythepilotplacard.php?clickkey=6452 If (1) the Pilot in Command takes complete responsibility for closing the door and then (2) hits it a couple times to make sure it is secure you won't have a door open in flight. It's when people in the passenger's seat., whether they have a pilot's license or not, "close" the door that most of these incidents happen. The other times are when the pilot in command thinks they have secured the door but haven't tested it with a firm hit or two.

I have had an Inogen since 2017 but there's not a chance in the world I would use it at FL180 and above. I notice that it starts to lose it's ability to produce breathing oxygen pretty rapidy above 16,000. I've used it up to 17,500 once. But in addition to that the FAA in their documents say that you have to use a mask, and not a cannula, at FL180 and above for good reason. https://www.faa.gov/pilots/safety/pilotsafetybrochures/media/oxygen_equipment.pdf

@SilentT I agree with @MikeOH, it might be worth at least an attorney demand letter for a few hundred dollars. When I looked at the pictures you sent me back when you started looking at this airplane, from the pictures the seats were at least an 8 out of 10. In that letter I would explain that to get seats that match the front seats, by the time you buy them (quote what factory new seats are), add matching upholstery it would be in the neighborhood of $5000. He may work a little harder to find them.

If I remember correctly those are the split reclining seats (at least they were on my '83 K model when I owned it from '93 - '96). They are in very high demand. People buy those from salvage to replace the bench seats in earlier models. It looks like BAS has one back seat available (https://baspartsales.com/140232-140231-mooney-m20k-aft-bench-seat-cushion-assembly-upper-lower/?searchid=0&search_query=mooney+seat) No matter where he is located, it might be worth a trip to his shop to look yourself. If he is on the West coast where you bought it, could a local Mooneyspacer go look through his shop for them? Bench seats are fairly easy to find (https://ebay.us/m/x0GUHF). I have no idea what all would be involved in putting in a bench seat. But @KSMooniac probably would know what's involved.

Friends don't let friends buy Gill batteries. Concorde has two sizes that will fit your airplane, the RG24-11 and the RG-24-15. You don't need the vented version (it has an "M: as a suffix), but you can use either version. Since you only have one battery on a J model it makes sense to buy the one with the best amp rating, the RG24-15. Chief Aircraft has the best price when you consider they cover shipping and they don't collect tax. A shop is going to charge you full retail on the battery. You can easily change this yourself, although you may need some help safety-wiring the hold down. You can buy the RG24-11 for $749 or the RG24-15 for $899.

It helps if you put that on your profile, that way on any questions you ask the answers can apply to your airplane. You have a very special airplane. Your Allegro is one of the last 19 J models ever made, having all of the continuous improvements over 22 years of production.

Here's the most recent thread about it: Here are some other threads about it:

A very common thing on 90's Mooneys is that the switch in the baggage compartment gets bumped after taking out luggage after a trip and the battery dies and gets to a low point where it can't be recovered. I did it once on a '96 Mooney Bravo. Later on Mooney wired in a delay circuit which turned the light off after 10 minutes. I would be surprised if a new Concorde battery didn't take care of your problems.

If it's at 22 volts you're probably not going to recover the battery. Has he tested your battery relay? What model/year Mooney do you have? Is there a baggage light? Was it left on?

The last Gill I bought lasted 20 months. I inquired about the pro-rated warranty. They were going to give me a $100 credit if I bought another Gill. Not a chance. It sounds like you have a dead cell. You don't need an A & P to change out your battery. Highest chance is that it is the simplest thing - a bad battery, especially since it's a Gill.

Is your battery a Gill or Concorde? According to the logs how old is it?

I think that was some tribal knowledge that disappeared when the original 252 engineers weren't around when the Encore was introduced in 1997.

Here are some other portions of that trip . . . I think:
