Your Requirements

II) Resale value is not important as I will drive it like for the next 10 or 12 years. (I rarely change car)

a. Camry - Good resale value
b. Accord - Good resale value
c. Teana - 2nd car dealer dont even wants it if u selling it after 3months of usage.
d. Subaru - worst than teana

III) Spare part easy to get (no need to wait months and months to order in) and will not cost me a bomb.
a. Camry - Available in massive & easily to find.
b. Accord - Available in massive & easily to find.
c. Teana - Available in massive & easily to find.
d. Subaru - Need to wait for import.

IV) Fuel consumption reasonable within class expectation.
All models are very similar. so no issue here.

V) Something that will not be too flashy to potential robber like a Beemer or a Merz.
Teana & legacy fits in here.

So based of above, Teana is your best choice.

Dont be too sure. it just that teana is the one of lowest theft risk among the selection above.
Sometimes crook steals the car just to commit crimes and no intention of selling it.

If already can afford RM250K car, actually for myself i would rather top up another 30k (total budget RM280K) and go for current Audi A6 hybrid.

based on his requirement ma, for maintenance bills, teana does better than legacy ma. he didnt mentioned anything abt preference on car performance or comfort also.
