I have absolutely no idea how to get my custom vehicle in-game. I've read the tutorial in the master sticky, but it says to get the XSI importer for 3DS Max. I have 3DS Max7 and can't find any plugin like it that works (the links on maxplugins.de don't work for me). Would it help if I revealed what custom vehicle it was?

It takes time and practice, you might have to wait for someone with the plugin to chime in and send it to you since maxplugins.de was the only place I knew of to find it. You could also try googling it, there could be another site that hosts it.
