Habu, I think that there will be no confusing the stinger with any other Kia model - or any other car for that matter!
The great thing about the R is it being so understated - everyone knows the GTi but few know what an R is until you hit the accelerator!
Interestingly the R has no
badge on it anywhere saying Golf - it only has a discreet R logo but everyone calls it a Golf.
BTW, if you are thinking of a Stinger take out a 3.3, the power / performance (not quite handling) could easily tempt you out of your R.
