pretty much what jaziba said.. except that i also need to take care of vstanced, have time for gf and job ;D on avarage it takes me around 12 working hours to do one car from ripping to finishing(not just the base) so logically if i offer one day a week to do this ill be done soon - 3 cars left and then small things like logos, load screens, video, menu/garage sounds etc..
