Following your build with great interest. Have the same kit (with the the Topstudio detail sets), just trying to find the courage to start with it :-). In the meantime hoping TopStudio will also release the detail kit for the engine, which seems logical since they already did the rest of the car.
Did you already find an alternative for the windscreen? I did manage to get my hands on the Acustion screen, but was informed by somebody that the fitting is very poor. Could go for vacuum forming it myself, but don't have the equipement for this yet.
Anyway, very impressed by your progress sofar, looks amazing!
