Well, from the past (my older PC), I had a nasty experience with mods, especially vehicle ones - as Matthias said, they looked fugly and pretty unrealistic; that's why I kept my San Andreas mod-clean until today... I checked this link Jerome gave (thanks btw) and there you can find plenty of awesome vehicle mods.
This one, first and only I've tried so far, is a replacement for the default Cheetah: a Lamborghini Murciélago LP640. It looks very awesome, has a nice design (even interior), lights, damage visuals, etc.
Thing is, since I don't have a lot of experience with mods, apparently I fucked something up. I replaced both cheetah.txd and .dff files using IMG tool 2.0, then rebuilt the archive. When I started SA:MP, the first time it kind of loaded a mix between the original game and the SA:MP. With this I mean, it showed first the GTA
an Andreas intro screen, with the spray can sound, but the screen was totally white; after that, it showed the SA:MP loading screens, etc., but the SA:MP mouse wouldn't show up. Then I closed it, re opened again and everything seemed normal... I don't really know what happened. If someone with experience knows why that happened, could you please help me? Thanks in advance.
Now, the pics:
1. Spot view
2. Closing doors. Really nice, it even has the Lamborghini's scissors style doors
