Make a car that would be the perfect car to pull off amazing stunts and tricks! 
Are there any rules?
So let’s see… Super fast, super agile… Probably super tough too. Well, I got the first two covered, the rest depends on the kind of stunt work.
LET’S DO THIS!
Not really any rules so yea… just create a car! Make it like this: 
I wanted to create a super hero car challenge but this comes close
Oh well! You can still create it. It may be similar, but it is not the same!
Closed here.
Reasons:
No Rules at all (i will complain if my 0.3L 40s sedan suxx…!)
No Purpose behind it (races? scoring? wut?)
No clear instructions (what to do with the finished cars?)
"Make a car that would be the perfect car to pull off amazing stunts and tricks! " is not a challenge… its something that would require arbitrary scoring, as that cannot be simulated in automation or a excel sheet or in any understandable manner.
Please take a look at how other challenges are made.
