How do you import cars to trackmania from the carpark

if you have TM united i don't know..
but if you have nations do this:

go to c:/documents/tmforever/skins

it may be you don't have a 'vehicles' folder, if so, you have to create the map
'vehicles'

then click the folder you created and then create the 2 folders:

1. stadiumcar
2. carcommon

(if you already have the 'stadiumcar' folder, you don't have to create it again)

download the cars from http://www.trackmania-carpark.com/ and put the files you downloaded (the cars) in the folder: 'carcommon'
