I would take the silver one.
That thing on the grey one's bumper is the old-style parking guide. It was popular in Asia.
If I go back home-home, I want to buy one from Japan lol. JDM SVX has 240ps stock and more high-tech features. The silver one looks nice to me and I ain't worrying about the OBD2 - I won't do a lot of heavy mods.
Just amazed how low mileages from the cars there.
