Need some ideas and suggestions in here. I'm new in this forum but not in the car world. This is my first post/question. See you often in here.

Nissan is one of the vehicles that car lovers want to modify. It's as easy as looking for some parts and you must know how to fix and put it in place. I'm looking for a complete Nissan Repair manuals for my dad. He always got problems with his Frontier. He always pays for some mechanic who can't perfectly do what he wants, that's why I want to give it to him for he can be the one who'll fix everything.

Another one, my sister's Sentra was used in some races, were looking for Nissan seat belts that's strong and can be used while you were joining some races and as an accessory as well. I know, all of our cars are Nissan. We all love the simplicity in it. Thanks for the idea in advance.
