Excuse me if my opinion comes off as too strong-headed, but I am begging you not to change one thing with this truck. That model, in any condition, is hard to find over here in the states.
It is absolutely beautiful even if there are some warts on its body. They are supposed to be noisy. They are supposed to be a challenge to drive. They are supposed to leak fluids. They are supposed to be smelly.
Enjoy it for what it is. It is an absolute gem.
