It's not funny to have any of your car appearing with meshes in its body. Now Zen-Imogen's Imponte Dukes Track-8 car mod 
s one of the cars that had a mesh bug. This mod fixes the meshes by changing the silver_spec texture to pure white color.

Required mod: Imponte Dukes Track-8 by Zen-Imogen

Installation: If you had installed the Imponte Dukes Track-8 mod, just replace its .txd. (e.g. if you replace stallion, which will
replace stallion.dff and stallion.txd in gta3.img, just replace the stallion.txd with this one). If you replace other cars (e.g. Sabre,
remember to rename the .txd file in gta3.img to sabre.txd)
