Mileage is a little high, depends what yor plans are.
It's not an original backbox. Looks more like a newage STi one.
P1 backbox is single exist round with 'P1' etched into the top.
Seat bolster is worn, which probably stacks up with mileage
HID are missing from fog covers.
Oh! and it's also 136 miles away, so needs to be worth the travel.
what about an STi Version 5 :
