If you search you'll find all sorts of opinions about the best way to go. You'll even find a couple of people who have actually DONE it.
I did my '84 Allegro earlier this season. I used Pergo Max in a pattern only available at Lowe's (Ironmill Maple). Time will tell how it will hold up to the cold, but it seems to be fine with the intense heat and driving around.
The original orange carpet smelled bad, was disintegrating from underneath as the result of several leaks and it was dirty and worn. Taking out the carpet is easy with a nice, sharp utility knife. I found that the linoleum cutter blades were perfect for getting tight up against walls and furniture. I took the toilet out of the bathroom in order to completely remove the carpet (the toiled was installed on top of the carpet - yuck!).
I put vinyl stick-on tile in the bathroom because it's a wet environment. I may do something else eventually. No matter what brand laminate you get, it will NOT like getting wet at all. The instructions on my Pergo floor say to wipe up spills within 30-60 seconds. In theory spills on the top of the floor should not make it down to the manufactured-wood base. What destroys the floor is moisture from underneath. The manufactured wood soaks it up and the laminate bubbles. I put down a 6-mil poly sheet over the entire floor knowing that leaks happen (and I have one in the area of the fridge that I need to track down).
Laminate eats saw blades like candy, so make sure you have a few. Follow the manufacturer's instructions and you'll be fine.
