I have my own opinions.
Great Cars: 4x4 Vegas(Move this car down the list to good, and replace with Vegas. 4x4 imo is an uncontrollable autistic vehicle), Pioneer, Dump Truck (Even after the nerfs) I don't want to include a car you can't buy. (Cars that everyone should have and are pretty much a standard in every mission.)
Good Cars:
Bishada, Jericho, Vegas.
(Great alternatives that still have their places and no HUGE flaws.)
Average Cars: Mikro (I also think this is a good car), Espacio (it's a good car), Cisco, Broadwing (Also a good car), Fresno(Also another good car), Coy Wolf(A 4 door mikro; good car), Vaquero, T-25.
(Average. Just average. Usually good at one niche and have one feature that stands out with no MAJOR flaws. Or has something that fills the role better.)
Okay Cars:
Sentinel, Montane, Han Veo, Calabria, Growl, Ceresco (This car is the only one that can actually be used for ram raiding due to it's storage capacity, it deserves to be average).
(Usually just all around bad or have numerous flaws. Or has something that fills the role far better.)
Ehhh Cars(remove this category): Ravan, Varzuga I'd move both of these cars up to the Okay because they are a decent set of cars for new players.
Broken Cars:
Kurai, Moirai (I have a hard time believing that this car is "flawed", I'd move it to average because the Broadwing is still a better car).
(Huge flaws and just all around bad.)
