I hope you had intentions on using the lug wrench to change the tire away from home.
If you don't have a sufficient amount of (at least) metric tools to do extensive work on the car, you'd better invest in a box and go to Sears with about $1000 or more or have a good mechanic. If you want to get into cars, you have to be equipped enough to do the work you're willing to take on yourself. Otherwise it will make you go insane not having something as simple as a deep socket or a breaker bar.
Good tools are your working hands and essentially are the limits to your working capabilities.
Don't waste your money on Snap-On, Mac or Matco unless they make something that you will get multiple use of that nobody else makes. Just stick with Craftsman for your hand tools. All you need is a lifetime warranty (which craftsman has) in case you bust something and money spent beyond that is a potential turbo, exhaust, body kit... you get the idea. Even if you break five 14mm craftsman sockets to one snap on, you can go and get a sixth. It doesn't matter if the tool is a piece of junk compared to something else. What matters is that it works. It's basic perpose is function. Not style.
Shiney tools look good in a tool box, but it does you no good to show off your blingy tools when your car is down or needs work.
My theory is that when you are using your tools, your car is less than appealing in one manor or another because it is being worked on (hence the tools), so who gives a shit what the tool looks like as long as it gets your car put back together, which is what you should REALY be showing off.
I just go with Craftsman for my hand tools because they are thousands cheaper than high end brand names and you only have to buy them once as long as you don't lose them (hence the tool box).
When you go to buy a set of tools, like a starter set, don't spend $$$ on multiples of the same tool that have different variations. If you can go without it because it's not needed or you can do the same thing with another tool, go without it. You don't need it. A lot of the tool sets you see for sale have multiples of relatively the same tool, even though they have a lot of pieces, they may be pieces that you will see little to no use out of.
In short: Save your first $1,500 or more for a good set of tools that you KNOW you will need and make use of. Stick with basic socket and wrench sets and move along buying other tools when you know what you need and try to buy them in sets to save $ and to build your capacity.
P.S. You have your choices of interior colors:
-Dark Maroon/Burgundy... whatever you want to call it
-Medium Gray
-Dark gray (almost black and almost non existant. Good luck finding one)
-Dark blue
That's a Toyota Supra for you. This is where creativity and upholstery and dismantling your car come in to play. Just plan on living with it or gutting it.
