Welcome to the forum.
Lovely cars, great choice
Generally very reliable with few things to look out for.
Firstly; corrosion on the A pillar, rear arches and back end of the sills and sunroof (if fitted).
Then usual service history stuff (when was cambelt last done, if not then factor in at least £150 in parts if you're doing it yourself or over £250 if you're paying someone to do it.
Rear calipers tend to seize up (though this is an easy fix normally needing nothing more than pads out and clean up/regrease)
Check all the warning lights come up on the dash and go out. Being a bb4 it won't have 4ws but could have abs, airbags and traction control. Bb1 has 4ws. If abs or the cel are lit, pull the codes so you know what you're letting yourself in for (paperclip is your friend here and check in our wiki for more info, including the full original Honda service manuals).
Vtec should engage cleanly in all gears once the engine has warmed up, except possibly first (depends how the kph/mph converter has been fitted on this particular bb4)
Front engine mounts go, check for any visible splitting. You can buy poly inserts for about 35quid or pattern replacements for about 60.
Check there's no flickering oil pressure light. If there is, walk away.
Ummm.. that'll do for starters off the top of my head!
If there's any forum member near you, they might well be happy enough to come and look at the car with you?
