Sorry for posting late.
Without mod to load custom cars, stock Flatout 1 can only load car 17 as an extra car and will need to add car 17 to cars.ini file. I'm not sure if stock v1.0 that come with Steam will load car 17.
I think you will need to patch v1.0 to v1.1 before car 17 will work.

Archives = {
[1] = "common1.bfs",
[2] = "common2.bfs",
[3] = "europe.bfs",
[4] = "driver1.bfs",
[5] = "chrisdodgeHz.bfs",
[6] = "blocker.bfs",
}
Also to trouble shoot, might just add each new bfs by itself in filesystem to make sure it work.
Archives = {
[1] = "common1.bfs",
[2] = "common2.bfs",
[3] = "europe.bfs",
[4] = "driver1.bfs",
}
