Depends... Whilst MoT length, followed by condition and price/budget are always the first priorities for most car purchases (especially cheap/immediate transport), understanding the differences between two given models can focus your search, especially if things like engine/gearbox (a 1.8 Vectra C is no use to anyone with an auto only license as they never made one) and cruise control or a sunroof are important features on the wish list... As Terry looks like running a fleet of Astra Hs, he might find it useful

The brochure will also tell you if items such as cruise are available options, and therefore if it's possible to retro fit it, which can influence potential purchase choices

Also, speaking personally, I find the brochures of cars that I am considering/or own and like to be an interesting addition to the car itself... Whether it's a late registered Omega or a £400 167k mile A Class. No I don't have any bumpf for the Focus
