For example, consider these:
STD 160 - 7 Tons - 39.9kph - 981,200 CB
STD 165 - 7 Tons - 41.1kph - 1,011,867 CB
STD 170 - 7 Tons - 42.4kph - 1,042,533 CB
Why would you ever buy the 160 or 165? The cost difference is one game's winnings or two games loss earnings, so unlike a real money purchase you can't say that the cost difference is an issue. Why are those even in the game? And there are a lot of these instance, though they are confined to the 100-200 range. 29 of the 122 engines (~24%) are, by all indications of the client, completely worthless.
