The GT was my first A-class car. I bought it for 50,000 credits. Little did I know that it would be a pain to upgrade. Acceleration of the GT is acceptable (though far from ideal and only with the nitro active), as is the top speed. Handling is above-average. However, the nitro is gut-wrenching and extremely inefficient, rated as 10/15/20, the lowest nitro efficiency of any car in the game. It also is a real pain to upgrade, as it will cost you a whopping 1,595,150 credits to max. Don't be fooled by the 75,000 credit price tag. So sad to see a beast get completely dissed.
