You guys are some real nitpickers! :P
Sure the liveries may not be great, but I think the fact that there's such a variety to begin with AND the fact that there's rotator AND LED lighting systems makes up for it and thensome. I like the different liveries. It reflects how a lot of IRL departments are right now, with a mix of older cars with older liveries and newer cars with newer liveries. Very realistic, they did their homework. They really paid attention to the police cars this time, we got what we asked for and maybe even a little more. I can't help but think while I cruise around seeing them that R* read our complaints about the police in the game and took them seriously.
EDIT: Also, I can't confirm this yet, but I'm pretty sure there's more unmarkeds than just the Vic lookalike. I do believe I remember a mission where I got chased by unmarked Buffalos of varying colors and perhaps even a Landstalker. That one could've been a Granger at a glance, though.
Agreed this are the best police cars i have ever seen on GTA V way better then GTA IV and Rockstar at least listened and added LED lights if they wanted to they wouldn't added it and just went back to the original police cruiser from that first GTA V trailer am actually thinking when the PC version comes what the point of modding these police cards they look great.
