The Deora is great, even makes a good drift car. Just needs some tweaking to curb some of the understeer.Yeah, I stick with stock "suggested" cars usually. I've exclusively been using the two Hot Wheels cars I have unlocked at the moment.
I"m finding the Hot Wheels tracks far easier than I did in Horizon 3, where I seemed to crash into the walls constantly. I like how they mix the tracks with "on ground" segments and have the 4 unique biomes. Enjoying it more than I was expecting based on my experience with Hot Wheels in Horizon 3.
