Cheapest country to race cars?

You can find a lot of cheap deals in emerging markets. For instance, my Thai friend buys high quality, custom suits over there for a tenth of the cost here in the states. So, it got me wondering if there are similar arbitrage opportunities when it comes to racing/driving: What is the cheapest country/region to race cars?

Obviously, there's no single answer since it would depend on a lot of factors: the type of racing (not all countries have road course tracks, for instance), the level of safety you prefer, whether you own/maintain the car, exchange rates - among a million other things.

To scope the question a little more: where are the best value "arrive-and-drive" experiences? Whether that's rally driving, formula cars, karts, sports cars. Just a cursory look at formula car arrive-and-drives in South Africa shows that it's a lot cheaper for a track day there than in the US.

I wonder if there are some obscure places out there where you can get a lot of driving for very cheap. Sounds like a Top Gear challenge...

 

Middle East was my initial thought as well. I was also curious about Latin America.

Maybe it was a silly question, but since I can often get free/subsidized travel, I thought it warranted some research.
