Holy god, you have done a great job here!
I really remember this set from my childhood, and this is actually not a cosmetic LEGO reconstruction set, so you can basically go inside it. I would reccomend though that you build the road to the garage by yourself, etc. using 2x2 print plates to make it look very smooth, as in the original and build the "01" and "02" on the same level as the 2x2 prints.
would rate 9/10, would increase to 10 if you are willing to try and see how my idea works.
Really good job!
