What are the best websites for buying new Kia vehicles?

I really need to get a new car by the end of next month because my old Honda finally gave up on me and the repair cost is basically what the car is worth at this point. Ive been looking at the Kia Seltos or maybe the Sportage if I can stretch the budget to like 32k but honestly looking online is making me so stressed out and anxious. I went on the official Kia site to build one and it looks great but then you go to the local inventory and its all dealer markups or stuff they dont actually have on the lot. Then I tried TrueCar because I heard it gives you a fair price but some people on Reddit were saying it just sends your info to five different dealers who wont stop calling you and the price isnt even guaranteed. I just want a site where I can actually see the real price and maybe even do the paperwork without sitting in a dealership office for six hours. Is there a better site for this? I saw something about Carvana having new Kias now but Im not sure if thats legit or if the warranty still works the same way. Every time I think I found a good lead I see a review saying the fees are hidden. Where are you guys actually buying these days?
