"How dreadful!" cried Lord Henry. "I can stand brute force, but brute reason is quite unbearable. There is something unfair about its use. It is hitting below the intellect." ~ Oscar Wilde - The picture of Dorian Gray
I have always seen Ford as an ISFP and Slartibartfast as an ENTP.
Similarly, I think Marvin is too insensitive to be an INFP. I have always seen him as an unhealthy, kvetching INTP. INFP could work, though.

I personally thought that Marvin seemed kind of INTPish... though that may be because he reminds me a bit of an INTP friend of mine
Ford seems rather ENTPish to me though- the rush in which he thinks and trys to explain things, and the manner in which he confuses people so thouroughly while convincing them to do things seems kind of familiar to me somehow
Zaphod HAS to be an ESTP though.
Human beings make life so interesting. Do you know that in a universe so full of wonders, they have managed to invent boredom? -Terry Pratchett
