But it isn't JUST a car! Its almost making me sick to let this thing go, warts and all.
In 1999, since my wife we pregnant with our first kid, I had to trade in my Dakota (reg cab) and get something safe for a baby.
After a lot of searching, wanting something 4WD, I decided on the Amigo--something most people don't even know what it is.
Think Jeep, but with more room. We've had a lot of cars since then, but have always kept the Amigo a part of the family. The last new car
we ever bought, or will buy, most likely. Had to twist the dealers arm to order it. Not only for an Amigo, but a 4WD. Not the average order.
Waited a couple of months and finally got it.
Brought home 2 kids in it over the years.
2 dogs and a cat too.
When my wife managed to drown her car when the road was flooded over deeper than expected,
I got to her and the baby in the Amigo, no problem, and got them out.
We went on road trips in it, easily fitting us, 2 kids and the dog for a weekend outing.
Went on trail rides from NC to TN to TX doing something exciting we'd never done before.
Lightly modified and had a lot of fun in it.

I don't usually have a hard time letting things go, in fact, I'm usually relieved to free up space.
Cars are different. There's not one I've sold that I wouldn't love to have back. I swear
they pop up in my mind almost every day how I'd like to be driving one or the other. I know I'm going to
regret it, I've had this one for FIFTEEN years, but at the moment this is the one that makes sense to sell. We bought my wife a car last week, so
we've got 4 right now and no room. Not to mention the monthly insurance adds up!
Still, this is going to hurt. Maybe no one will buy it? Hmmm...

Oh, that sucks.

Wasn't that the one with the commercial of it running through the mud with the top down and a big monster sitting in the back just bouncing all around?

That's a first gen, but that's it. There was also the abhorred Amigo-slinky song ad, but that's treated like Highlander 2 and best not mentioned. LOL
Tough little beasts, we've had a lot of fun in it. I hate change. LOL

This car looks amazingly familiar, at least the taillights do, I think they're branded and sold as Opels in my country.
It seems like it's a very nice car, can't you just park it in the garage and uninsure it until you want to drive it again?

It was sold pretty much everywhere. Vauxhall/Opel/Holden Frontera or Wizard (Rodeo, 4 door version) or Frontera Sport, Mu(?) for the Amigo, 2 door.
Fairly rare, especially 4WD in the US for the 2nd gens.
We don't have room for 4 cars. Of the remaining 3, one will be for my son's use in a year or so when he's driving. Plus, I want to get a fishing kayak & a trailer and we barely have room for that.
Something has to go and the Amigo is the one worth the right amount, needs some money put into it (a/c) and 3 cars is enough to keep up with. It's the right time for it to go, but still going to be odd not having it.

Curious what the car is that your son will be getting as this seems like the perfect first car for your son.
Also check and see if any extended family members or friends might be interested in buying it with the stipulation that you get first shot at buying it when/if they decide to sell it later on.

Good Luck and we all have cars we wish we still had (or cars our parents had when we were growing up, that is a nice list for me).

If I have my way, the Miata I've been messing with and picked up cheap. I'd rather our kids drive a manual at first, and preferably a 2 seater. Fewer distractions in the car (friends) and you can't text and drive in there. The Amigo is a stick shift, but I've already put money into the Miata, and kids tend to get in even more trouble around here with a 4WD.
Our Honda is worth bit more, but I'm saving that to sell when I look for a truck. In the meantime, it's the better car to hang on to. I'm trying to be somewhat responsible here. LOL
