Kit Review – Mercedes-Benz 300 SLR

August 18, 2012

by Iggy Perez

The real car was actually based on a Formula 1 car from the 50s – not on the well known 300 SL. It was specially developed for racing in the 1956 season, but it never came to the tracks. As it seems, the reason why it is called “Uhlenhaut” is because the designer back then was named “Rudolf Uhlenhaut”. If you wonder why is the front so long, then my guess is because this car had a 8 cylinder in line engine – the same engine used by the world champion Formula 1 car in 1954 and 1956 with Juan Manuel Fangio behind the wheel. The top speed was 190 Mph or almost 290 Km/h – there is no typo there. This car, however, never came to mass production and apparently only one of the two cars built was ever driven on the street – by Mr Uhlenhaut himself.  Kind of cool, if you ask me.

The scale model kit is pretty realistic – with the limitations of a 1/25 kit. The moulding is good, but there is a lot of sanding to be done – at least in the kit I have. There are many seams on the body and some excessive material here and there on the rest of the parts. Oh, yes, the gull-wing doors work – nice! But the hinge mechanism (just a little plastic tip on the door piece) looks pretty fragile.

The parts, in general, are very well detailed. You may see what I mean about the excessive material on the steering wheel, low right corner of the pic. Otherwise, the parts show very nice moldings and seem to be accurate. Anyway, who of us is going to comparte them to the real car…. with only two ever build back in the 50s 😉

The chromed parts also have some of that excessive material here and there. Which is a bummer, because you have then to remove the chrome and re paint them with alclad. On the other hand, the alclad chrome may look more realistic than the scale model chrome. Anyway, there are many cool parts in the chrome three: the rims are made of three parts each, one for the outside, one center piece and the center nut with the Mercedez Benz star. One thing that I also liked are the wipers – I really don’t like it, when the wipers are moulded onto the body.

The decal sheet has some useful stuff there. First, the seat patterns. I guess not everybody could paint that kind of pattern in such an accurate way. So a decal helps a lot there. Second cool feature are the gauges. I learned to like the decal gauges. The chasis number plate looks pretty cool too. Bad news is, that this car only comes with Swiss and (old) German license plates – no US plates, but you can always print your own of decal paper.

I like the wheels too. They are nicely moulded and the lettering isn’t too heavy. The path looks right to me as well.

The instructions aren’t that good, though. What I dislike a lot is the fact that the colors are referenced by numbers. You can always have the reference table next to you, I know. But what’s the point? If you have to look back and forth all the time, the instructions don’t become clearer by avoiding naming the colors.


  • Nice accurate reproduction of a cool, historic car.
  • Decent amount of parts: 124.
  • Generally well moulded and with many details.
  • Some useful decals.


  • Lots of sanding and cleaning up to do there.
  • The instructions don’t seem handy to me.
Conclusion: if you are looking for something different to build, this may be the right thing for you. After building several “ordinary” classic cars, you all know what goes where without looking at the instructions. This car, as a one of a kind in real, is also a one of a kind on the model building and may come as a bit of a refreshing change for you.
