i will start from personal experience my cousin got a 2006 Toyota Ractis last year, it is such a joy and comfort to ride, but when it comes to maintenance it kills a lot of time and precious money. Its Front suspension has a rubber mounting like city idsi, it needs replacement couldnt find it any where and with its current mounting its front vibrates on high speeds. now its headlight is broken when it was parked (it happens all the time in pakistan) we have got qoute of 16000 for one peice from Bilal ganj lahore. if we change one light their color is not same and pair costs about 25 - 32 ks, And i wonder no body mentioned that but vitz and ractis are the two cars that i know are fitted with special spark plug that costs 900 rs a piece while all oue local cars are fitted with a spark plug that costs only 150 - 200 per peice.
Conclusion considering your profession get a local made brand new car (Cultus, or Swift will do the best for you) enjoy it for four five years and then do whatever you like.
