I last read this trilogy-in-five-parts forever ago. The first few are as funny as ever. In contrast the concluding Mostly Harmless is a bit dire, with the foxy Fenchurch killed off before the action (as it were) begins. I always wanted to know how the dolphins left, where they went and if they ever made much use of the Guide. While Adams spells out enough of everyone else's (sex-)lives, Ford Prefect may well have been a humaniform car given the action-man he morphs into.
