Time to change a new ride?

I have been driving our family car, Mit Lancer 1.6 GLX for almost about three and a half yrs (coming July will be 4 yrs). My ride has always been very comfortable and this Lancer has been with me since I was in NUS. It has accompanied me in every big and small events e.g. during my studies, pah tohing with ger, with my new company, used it for our wedding too...

Really can't bear to change another new car. But then when this car gets older, its value will drop and FC isn't as good as before.

So thinking of whether now is it a good time to change a new smaller cc ride where I can save on mainly the fuel, road tax, and insurance.

Went to a few car showrooms last Sunday to test drive a couple of cars.

Cars tested:

Suzuki Swift 1.5L
Suzuki SX4 1.6L
Toyota New Vios 1.5L

Honda Jazz 1.4L 2007

My humble opinion after test drive:

Swift is a zippy car but small in build. I like its look but may not be suitable for us if we have kids next time.

I love SX4 but thinking of the road tax, fuel consumption, I dropped the idea of getting this.

Vios got a noisy engine during acceleration and the Toyota SE doesn't seems very enthusiatic in selling Vios and does not seems to know a lot on Vios. It's a Tom Yum car and we can definitely spot the differences between a Jap-made and a thai-made one.

Jazz to our surprise is a very spacious car as compared to some others of its same criteria. Definitely enough space for 3 person to sit comfortably at the rear seat. It also have a sporty look especially with all the bodykit fitted and when it is yellow in color.

Hmmm.... Which one should I choose???
