Installing the performance air intake today made me realize I am in desperate need of a tool set that is not filled with random tools and very few metric tools. Right now Sears has their tool sets on sale for 30% off. I am looking to spend between $100 and $200. I want a set that I can keep in my trunk and use for routine maintenance. I don't plan on rebuilding any engines or doing major repairs myself.
What tools are absolute must haves for the set I buy? Are there any that, while it is not a must have, would be nice to have and make my life easier?
