I've got both Vitz and coure at home, I don't think that is even a comparison if you compare comfort and safety. I've got a 2006 1.3L, and it does 13 kmpl in city, and around 15 kmpl on highway with AC, no hyper-miling. And during the course of 18 months of owning it, I've just changed water pump because its bearing got noisy for PKR 3000, labor included. It's a daily driver, runs around 1000 km/month.
If you don't have financial constraints, I feel they is no reason to even think of coure. If you're skeptical about resale and mileage, you may opt for 06~07 city.
