Wow, I am really delighted by the performance of the Presto! The challenge was a real nail-biter and turned from “I hope it is going to be top 5” to “the others will have better stats” to “I think I can really win this” for me. 
There have been some truly nice cars I have been afraid of.
Here’s the car for anybody interested: 70GT_-Der_Bayer-_Cisalpina_Presto_72.car (85.3 KB)
I haven’t opened it again, but I think the biggest “exploit” was probably that it is only a 2-seater, which saved some weight, cost and increased performance and comfort. It was a 1972 model year - I don’t know, what exactly that did for the final scores, but maybe it also saved a bit of weight and cost.
Thanks @karhgath for a very entertaining and exciting challenge! I can only imagine what an effort this must have been!
