The price difference between a new Myvi and a 2nd-hand Corolla will offset many years of petrol money. Even more so if he chooses to buy a 2nd hand City or Vios.

Then again, I'm quite sure the fuel consumption difference between a 1.6 AUTO AE 111 and 1.3 AUTO Myvi is not much. 1.3 Auto Myvi is well known for it's somewhat high fuel consumption despite its small engine.

However, 200,000 km mileage is a bit high and I suggest you try looking for one with lower mileage. Get a manual one if you don't mind, the fuel consumption difference is quite significant especially with older cars and gearboxes.

As for space, I have to testify that the Myvi at least FELT more spacious compared to the Corolla. I think it's because the Myvi has better legroom and headroom, although the Corolla has a wider interior. As for boot space, the Corolla can carry more bags but if you need to carry very large items, hatchbacks are still more useful.

Wah, gearbox also! I heard original UMW parts are really expensive, according to my friend who owns an AE 101 SEG.

Anyway, 4AGZ-E and K3-VET are a different class of engines already. Might as well don't talk about FC if you're going for those.
