Modded car from Mafia 2 Classic in Mafia 2 Defintive Edition looks like chameleon, well that because Mafia 2 Definitive Edition has another paint textures. You need to copy all dds files from extracted original Mafia 2 Definitive Edition model and copy & replace to your extracted modded car. Copy and replace/paste entries responsible for textures in sdscontent.xml too. To do so, double click on sdscontent.xml to open sds content editor. In that editor click option Tools and then click Auto-Add files. If a warning message appears then accept it. Then select File and click Save. Go back to cars folder and pack sds file back.
Mafia 2 Definitive Edition uses FSB5 instead of old FSB 4 used in Mafia 2 Classic. Mafia 2 Definitive Edition can't load FSB4 type sounds, so you can't hear the car sounds. At the moment it is not known how to create new fsb5 file to make them work in game. Therefore only way to fix sounds is copying original sounds from Sound_Table folder inside original M2DE car sds and replace them in modded car sds.
