Pretty much the same as with buying a second-hand vehicle.
If you are referring to the JDM Civics which are imported, check the steering conversion carefully. If you think or see that the conversion was not properly done, you can always get a new oem/replacement or surplus rack & pinion and steering box locally.
Give us more details about the unit like year model, condition, mileage, etc.
Common problems on the EK bodied series are suspension bushings, stabilizer link, trailing arm, power windows (weak), power locks, door hinges. For the engine its usually idling and valve cover seals.
But don't get discouraged because these are just as common in other brands. Low cost solutions are readily available, sometimes you can even DIY .
320k is an acceptable price for year 2000 and up models especially for VTi's, again it depends on what the owner has done in maintenance, mods, servicing.
