After looking at Nick's pictures (I still have not seen an actual Spark), I'm thinking it might be best to hold up on ordering traction mats. It looks to me that the foot wells are already textured, which may or may not be sufficient, I would at least try before I buy traction mats. The other thing I noticed is you might have trouble getting self stick mats to adhere to the surface, and if you use glue down mats it's probably going to take a lot of glue, making a mess for the next time.
Just my thoughts.
