the green one is my fav!

Great cars my friend! The lime green one is my favorite. -LB Jr.

The shape of the second one is great.

Cool little cars! My fav is the lime one. Can't wait to see the Audi! :)

31000 is not a great kit. Some useful parts. I combined a couple of them to build something else (Bumper Car on my page). Maybe a couple of other bits chucked in there too. Otherwise, sorry Mr. Lego designer, 31000 ain't that good. Your white one is good by the way DeT.

Great alternative builds.

MMMM... I think I have saw this Audi before... Maybe not :S

Very cool alternatives! I can't wait to see that Audi when it's complete!

Great alternatives, and looking forward to what looks like a very smooth Audi :-)

Yes! Another car from you! Not to sure about the model, but I'll say audi like the others.

Obviously an older Audi, but like everyone else, I am clueless as to which one. Still, looking good!

Nice alternatives Tom! With your sneak peak, is it an Audi quattro?

It's a- I already know, so I won't spill the beans. =P Some cool alternatives there, My fav is probably the limey one.

Awesome! i need the mech, and want the car sets! the best is the green one (imo)!

I like the black and green one best!

Awesome! I really like how you used a lot of smaller pieces to add a lot of detail to the cars!

nice these look realy cool keep posting great things!!!!!

Nice alternatives! The Audi is quite obviously an Audi, but like Alex I'm not sure what model! Old(ish) A4 or A6 maybe?

Haha, I have no idea why the Rubiks is there I am hopeless at trying to solve it. I scale my cars around the wheels and details like the headlights etc. I look at the cars wheelbase in a picture and measure the amount of wheels there are between the front and back wheel, it's not always 100% correct but I find that is the best way to scale things. Thanks for your comments :-)

I don't know what model it is as I am not that good with Audi's. One question why do you have a rubics cube in your work space? Also how do you scale your cars?

Very nice alts. The 31006 looks like it could be a hot wheel car! ;) The Audi looks absolutely awesome! Can't wait to see it finished.
