It has come to my attention that we don't really have a decent 2-door police car.
We do have the police turismo which is available for donators with a wrap, but to be honest, it's really not the best vehicle to go after criminals and pursue them because its handling is awful, therefore I'm suggesting to add a new police car mod (basically sirens) with 2 seats, which is Cheetah.
You probably all know when you get wanted for 6 stars in Vice City/San Andreas, some high profiled agents show up in a black police cheetah with sirens on, so it's a good choice, why not? I mean cops can already use the normal cheetah while patrolling, but wouldn't it be even more cool and RP-ish to be able to put sirens to it?
It could be available to get as a donation reward or even as a squad reward, and the vehicle's acceleration, top speed and handling would be just the same as any other cheetah with v8 + awd, so criminals can't complain and it's equal for both sides.
