you are definetly improving. keep going!

Just like Ape said, if you want to improve your model based on a real car, get some pictures of the real one and take a close look at the shapes. Sooner or later you will find out the differences and be able to work on them. For example the side view of your Passat Variant looks more like a Scirocco than a Passat Variant. There is no space for two doors on the side panel. Considering the height of the "waist line" your model also should have been a 2 or 3 studs wider. For your next project you might take a look on this site, it's the best tutorial for LEGO scaling I know: http://wiki.ldraw.org/index.php?title=Scaling_Down

Too bad you destroyed it already, I think it just needed to be a bit more rounded, particularily in the front.

As with all the posts on MOCpages like this one; Put a picture of the real car against your model. Then play 'Spot the Difference'. I can see at least 10 things... Keep going, you can rebuild it many times : )

Its a shame you've broken it up. It just needed more detail on the top, like Marcel said, it needed pillars to separate the windows, and thicker c pillars. other than that, it looked great, so it is a shame you got rid of it :(

Well Marcel, I have torn it apart. I am building a fictional car a small hatch back with sliding doors!

DON'T PULL IT APART. Make the rear longer and add some supporters between the windows,so instead of having 1 window on each side,you have 3. Wagons usually do. And add some black plastic pieces on the top to make it look like rails that are usually used on wagons. Glad I could have helped ;)

Hey, this turned out quie nice. But here are a few tips. First of all, make the back pillar support 1 stud higher if you can, or find some way to make the C-pillar taller, if you get what I mean. I know the rear of the 2006 Passat Variant slightly gets lower at the rear, (my family owns one) but still... At the moment the car looks a bit like a shooting brake, like my Ferrari FF. Then, if you can, turn the roof back up the right way, and attach a B-pillar behind the rear doors, one stud in front of the rear wheels. Hope this helps. Oh yes, if you intend on making a final version, call it Passat Variant, not just Passat.
