One of my first LEGO sets was 6811. M-Tron was cool and I would love to get a good deal on this one. They don't make sets like they used to.

I got this for Christmas when it came out. Still have it. Still love it. Built it just last year. Amazing set!

Awesome!

When I was a kid I thought the M-Tron commercial was cool.

Loved the giant wheels and huge transparent canopy. I remember trying to remake this set using Spyrius colors as a kid because that was the only set I had with that giant window part.

I really loved how Lego incorporated the magnets with the MTron and other sets; I think the Ice Planet sets did that, too.

I bought this set with box during Lego World 2009 for 35 euro.
Great set, lots of play features and a good looking vehicle.

OMG! This is the only set I am missing from the M:Tron Line. however - it is sure the best one. My friend has this one. On One Christmas dinner with friends he took it from the attic to show to the others. All the adults were absolutely amazed!

This was one of the sets I got on clearance at a Los Angeles Target Store in January 1991 during a torrential downpour. I paid $30 American for this beauty!
(And $60 for an Airport Monorail, and $30 for a Model Team truck with helicopter on a trailer. That was the most amazing clearance ever!)

One of my all time favourite sets. I used to stare at this set in LEGO catalogues as a kid dreaming about owning it. Sadly that never happened and it was one of the first sets I made sure I bought when I left my dark ages and returned to the hobby many years later. Life lesson learnt. Don't give up on your dreams they can still come true, even if it takes 20 years.

I got this set for Christmas as a kid and loved it, spent full days playing around with it.
I still have it, in assembled condition although some magnet holders and one of the plates are broke, got to replace them.
An awesome set I am still proud of. :)

I have this. It's my favorite LEGO set ever!

@sirventricle My white whale as well, I really wanted this as a kid. Still do.

I came across this larger version someone made. The video is made like a commercial.

I was expecting it in the Random Set, but this is faster than i thought There it is, my favorite Space set and one of my favorite sets ever. I've still got my original from when i was a kid. Rebuilt it when i moved into my home, with some replacement parts from BL. Such an awesome set, so much playability.

One of the all-time classics. Having a set with this much size, detail, and playability almost makes up for the lack of a base/building set for the M-Tron line; M-tron is a mobile force, and MCM is the ultimate example, I guess.

I have a picture someone once took of a fleet of MCM, with examples redone in all the different colors of Classic Space themes. The canopies and huge wheels make this a difficult project to complete with any type of reasonable budget, but I'd love to do this someday.

It was neat to see the Mars Mission theme come out with a version of this vehicle several years ago (7699), complete with mini-ship and mini-car vehicles that fit into the chassis for long-range transport, but it could not match the charm of the original.

One of the first sets I bought on eBay after coming out of my dark years.

@Lyichir thanks for that hilarious, and horrible link. That commercial was straight up whack, and that's a fact lol. I ended up watching another video showing about 8 min.'s (20 years) worth of LEGO Space commercials. The first ones were great, they definately had their dark ages in the 90's, and came around again after the millennium. So, kind of like my LEGO collecting :)

I personally think the old commercials have a special charm. I can't stand the new computer generated commercials for City.
Anyway, as everyone else has said already, this set is so awesome in so many ways. It's one of those sets that you can get multiples of and make some pretty awesome MOC's with (the large neon green canopy/windscreen and the giant sized wheels were unique to this set at the time).

A couple years ago, when I set about rebuilding my LEGO collection from when I was a kid, I purposefully saved this set for last. This was one that when I got it from my grandmom, it got "saved for a rainy day" on my mom's advice as I'd gotten several other sets as well. As a result, I think it got built once, maybe twice, and would subsequently get ripped apart to use as a basis for all sorts of MOCS like exploration vehicles or war wagons for the never-ending fight against Blacktron. There were plenty of other sets that were used as fodder for builds, mostly Star Wars sets like X-wings and TIEs. This was mid-90s before SW sets hit right as I got away from the hobby in high school. No set had as much time not fully built as the Mega Core Magnetizer, though.
Now, during this period of rebuilding my old sets, I bought plenty of modern sets as well, as I've now been fully in the throes of enjoying it again. Working at an LBR store for the last 4 years has certainly fueled it, and now I have a young son who I'm looking forward to introducing LEGO to. It took time and patience and BL orders to replace parts and instructions that I no longer had, even though I had 95% of parts and instructions still. So I concurrently had time to build newer sets like Slave I, the Technic 24-Hour Racer, the Helicarrier, all the Creator Expert Vehicles, all the modulars, among plenty of newer sets. So when I finally got to the MCM, I ended up being a little disappointed. Nostalgia is a very, very powerful thing, and while I continue to be impressed with how voluminous those old sets seem with just a couple hundred pieces (6985 Cosmic Fleet Voyager, anyone?) it definitely shows its age. Still, despite very much being a product of its time, I would say that MCM encapsulated the best of those 90's space sets.

Yeah, baby! This one's -still- near the top of my wish list! M:Tron was such a great theme. I have all of them but this one--some day, some day...

Picked this one up in a Charity Shop a couple of years back. I paid £4.99 I think. A few parts were missing but these were easily 'Bricklinked'
A great set!

I did not have this one, but two of the large spaceships. It was some of the last thing i bough in space themed series. Before later tried some Star Wars before i went to my sleep dark age.

I have recently got some parts from one set, and going to complete the set over time.
