I agree with you, the MP-8 with is pure lines is one of the most beautiful F1 cars ever.
For my the most beautiful and originals were the cars from the 70’s, when there were no such big restrictions as they are today and the designers had more freedom to create, now they look almost a mono chassis championship.
Really nasty defect in your F312.
Not usual in Tamiya kits.
In all this years I only had a missing mirror in an Escort RS Cosworth and a Michelin tyre instead of a GoodYear in a Lotus 79.
