I wouldn't suggest that particular model of either, cultus is a workhorse but lacks basic creature comforts it is not insulated well and the only redeeming quality is cheap parts and a sold engine, chasis is solid as well but unless you want to haul industial supplies and use it as a mule there is no valid argument left for owning a cultus esp when the prices are on par with some 1300cc cars.
2006 Civic is excellent, go with an automatic if possible and spend 1-2 lacs on it to add some life to it, it should last you atleast 3-5 years.
