That's quite an impressive modification to the International Transtar II! Boosting the power up to 900hp and increasing the maximum speed to 150 km/h must give it some serious performance on the road. The added power will definitely come in handy for hauling heavy loads or tackling tough terrain. The price of €45,000 seems reasonable considering the enhancements made to the truck. It's great to see these kinds of modifications available to players in the game, adding a new level of customization and performance to their trucking experience. Do you have any more details or features to share about this modified truck?
