Hybrid battery life is more than or equal to 300,000 Km.. I know people who are nearing 400,000 km and still battery is good..
2 main categories.. UK and Japanese.. UK has English software... but resale value is LESS + HEARD from some people about heat-up issues due to smaller radiator.. Japanese ones.. language is in Jap.. but you dont need to interact much, + Resale strong..
So in Japanese...
There are many version.. Simple S.. S multi.. S touring.. G.. G touring.. 10th anniversary
Best are G Touring and S 10th anniversary
G touring edges = 8 air bags, leather seats, 8 speakers, but HARD suspension, so you would feel at bumpy roads
10 anniversary = 2 airbags (didn't check for all 8 ), 6 speakers, suede seats (Very comfortable), but a softer suspension, trademark of TOYOTA..
Additional accessories are Smart entry, smart start, bluetooth, auto parking, etc etc they are additional.. and CAN be or not on both these..... MY 10th anniversary has all of them..
My personal advice would be to go for 10th anniversary edition
