I do not know if it's serious or a bad joke.
The file 7.z has two files with which you can not have a car. There is no trunk and / or nose. The only number that appears is the 18 (Lance Stroll), in Williams Kubica (88) and Russell (63). There is no shape and the files even if they are ALL do not match the 2018 shape.
Excuse me but I do not know, either, which work they praise because this is NOTHING OF ANYTHING.
If it's a joke, as I said before, it's bad and it's wasting time.
And if those who praise do so because they believe that what they will find is SOMETHING, it is better to look than to speak.
Best regards.
