The following vehicles are known to spawn at the locations described below. This list covers both the GTA 5 offline and GTA Online car locations.
Note, you are also able to buy cars in GTA Online (as opposed to stealing them). This can be done by opening the internet browser on your in-game mobile phone (Eyefind) and then going to the Travel and Transport section. There you will find links to the four different vendors of vehicles within the game: Benny's Original Motor Works, Legendary Motorsport, Southern San Andreas Super Autos and Warstock Cache & Carry.
Modded Dubsta 2
Extremely rare
The modded Dubsta 2 is an extremely rare spawn and requires specific actions to be completed before it can be acquired. Refer to this article for specific instructions.
Rare The Obey Tailgater will appear in the parking lot of golf course in the area shown here on the map. However, it will only appear if you've received a text message from Simeon asking you to get it.
To make the Canis Bodhi spawn, you must either host or join the Rockstar-created Mission "Dirt Road." It will then appear in the location shown on the map, between rocks on the road.
You can also buy the Canis Bodhi for $25,000 from southernsanandreassuperautos.com.
Canis Mesa

You can also buy the Karin Rebel for $3,000 from southernsanandreassuperautos.com.
Karin BeeJay XL

The Karin BeeJay XL will be outside of the Criminal Records race in the area shown on the map.

You can not find the modded version of the Sultan RS naturally out in the open world, but you can find the normal Karin Sultan and upgrade it to the Sultan RS. There are two guaranteed spawn points where you can find the Sultan RS. The best part about these locations is that the car spawns in a group of either two or three!
The first location is the Prison parking lot. If you do not find the car then simply drive around the prison and a new set of cars should appear. Try it out a couple of times and if you still don't see the car then simply find a new GTA Online session and repeat the process. We found the car after two session changes and driving around a couple of times
The second reliable location is the Maze Bank Arena parking lot. You can find the car in the parking lot of the arena. If you do not see the car, then repeat the same process of changing your session and driving around the stadium to refresh the cars.
It has also been reported, by a number of players, that if you drive around these locations in an Elegy RH8, then the likelihood of a Sultan spawning is higher... and, there is no harm in it since you can get Elegy RH8 for free.
Now, to upgrade your regular Sultan to the Sultan RS, you can either go to LS Customs and add a Roll Cage to get the RS version, or go to Benny's Original Motor Works and upgrade your normal Sultan to the Sultan RS by paying a hefty GTA$795,000. Also, when you go to LS Customs, you will need to add all the performance upgrades to actually turn the car into a proper RS with improved acceleration and handling — adding a roll cage is just for decorative purposes!
