Yes I do feel your pain, the GT I believe is a 200mph vehicle. It will get up to 138mph so fast, then cuts off! I have been in touch with the man that is over the whole Pacific north and south west kia Corp, he told me under NO CIRCUMSTANCES will Kia change the speed limiter!!! He was a real piece of shit, he had a smart mouth, and a head full of rocks. He is the kind of person you pray you run into, to see if he would even try to run his mouth so wreckless to your face. I could not understand how kia would let some one like him even buy one of their cars, much less represent their company, because if they don't run him off, I'm through with kia, and will tell people on the street I don't even know, dont buy a kia. Which I do!! I get asked all the time, how you like that stinger, and I tell them how kia lied about how fast it would go, and what sorry premium customer service they have..... I have the only one of these cars where I live, and unless kia makes some things right, i probably always will. I met Sam Walton when I was 16, I watched him fire managers that would dare challenge a customer, and insinuate that the customer was wrong, his ideas created a empire. Not kia!! That Rep. For the Pacific told me I was stupid for not investigating the top speed better, yea I could see a dealership letting me get up to 167mph, just to make sure they are not lying, before I bought the car.. maybe somebody that really wants to sell cars will take over soon. And make this right!
