Just bought this lot. For the price (under $140) I think it was pretty good!
Biggest city in the world, Mexico City, Mexico! 
That is a great find indeed. I didn't know turbo games were sold in Mexico. Just curious, did you get that at an open market or a video game store?
Oh yeah, TG16 was kinda big in Mexico. TG-16, CD unit and games were officially (like with a licensed distributor) sold on a big department stores chain over here, called Liverpool, something like Macy's or Sears in the US. Then when Turbo Duo came out, some stores like "Gameplanet" (they operate still to date) did took special orders from some gamers, and I bought my Turbo Duo and many games with them. Liverpool never brought the Duo or anything TTi related, guess the TG16 sales were not as expected.
I got this lot from open market, it's like the mexican version of eBay over here (I think they are actually associated) called MercadoLibre. From time to time, great deals like this one can be found there. Most of the time everything is overpriced, but this is proof that sometimes you can hit the jackpot!
