my mate had an s14 when i had my 190bhp 172, his was running a few goodies (hks manifold, nismo injectors, front mount, nur spec R and decat, boost controller) estimated around 300/320bhp.
straight line it was mental, would see off most things you will meet on the road! my mate got to about 160mph when he backed off as he was getting scared lol, handling his was on coilovers but you would be surprized for a big heavy car it handled VERY well it was having the balls to push it, very rewarding to drive quick where the clio is so easy and forgiving to drive quick, you respect the 200 as you know if you push that loud pedal a bit to much in a bend your going backwords!
as for what car would you want to do a long trip in, the 200sx is a mega cumfy big cruiser, full leather etc, dont know what they are like standard but my mates was MEGA thirsty
i love them and was seriously close to buying my mates before he sold it, thru the bends i could keep up in the clio if i really really pushed the clio but in a straight line it pulled on me like i was in a 1.2!! and on the motorway, not a hope in hell lol
