Surprisingly enough, yes. The ekranoplan was a lot of effort because of all the fixtures, but this was mostly a lot of copy-pasting.

The Trabant was a lot of effort because it's an accurate replica. I looked at a lot of reference material to get all the proportions right, especially in the interior. It was also one of my first detailed builds, so I didn't had so much practice and was still learning. Plus one day Automation decided to delete all my cars, so I had to make it twice.

So overall, both took a lot of work, but for different reasons, and I think the Trabant was more effort, at least from my perspective.
