I'm new to Blender and got the following problem.
I also checked and tried the solutions as described in these threads.
But none of these worked as I always get "Removed 0 Vertices" when I use the command "Remove Doubles".
Right now I am using the v2.79 of Blender. Also the file for this car is uploaded here.
I would really appreciate if someone could help me out on that. Maybe some other people have the same issue...
