Nice cars, the roadster is my favorite, never found that red and yellow worked very well together, but obviously I had never seen it on the right car! The yellow car is good too, although it feels a little too short compared to its height, IDK, this might have been intentional. It took me a while to find something of yours that I hadn't commented on yet! Hope your not too busy, keep on building man!
These are pretty good but I think a few things could be changed. The red car is very good but the yellow seats don't really fit and the windshield doesn't look right. the green car is nice like the color but it looks a little boxy. overall still very nice.
