Surely they get the best vehicle possible (for their rank) which in most cases is the 3 door cruiser and very rarely do they get a VIGO. Almost all the regional offices have some good cars available but keep in mind that "the best possible" scenario holds true for the senior ranks as well hence the newly appointed ASP's just get the best available from the remaining lot.
Please don't drag this topic anymore, everyone knows that although the civil services has it's perks and privileges but it can never compete with the private sector on these things. It's one thing acquiring information to judge whether you can survive on the salary and other benefits that one is provided during your service but basing your judgement on the model or the kind of car you get is downright shallow (with all due respect).
