Ok, so these guys have now spent several thousand of your dollars. Much more, if you count the truck.
I am gonna suggest that you need almost none of it.
If your goal is to have a nice shop, you need it. But if your goal is basic maintenance, you don't.
So, here is my suggestion.
The total amount being suggested here is between $3000 and $5000, plus the truck.
Put that much money in a checking account, and don't tell your wife. Contribute an additional $100 per month, because you must have a maintenance budget.
The first thing you are going to buy with money from your maintenance account is 2 six packs of beer. Don't buy the cheap swill. This is not for you- this is to share with the local handyman on a purely social level. New to the neighborhood, get to know 'ya.
Shortly after you get to know the handyman, ask him occasionally to borrow tools for basic repairs. This makes him feel important- he likes to help. Make sure you return the tools the same day, preferably in better condition then you got them. This makes him trust you.
Now, give your wife the handyman's number.
Use the maintenance account to pay him whenever she calls him. If you play it right, she'll think you are a hero because you are always prepared and can handle the llttle things.
He won't charge you much, because he likes you. You will NEVER spend all that money, and you will never have to lift a finger.
One more thing... Don't call it your maintenance account. Call it your "I'm a berkeleying genius" account, and smile to yourself every time you use it.
The only thing buying a bunch of tools does is clutter your life, and give you more E36 M3 to take care of, and a much longer "honey do" list, and more stress and unfinished projects.
