If you own an e30 and your not rich (rich to the e30 community is pretty damn low) chances are you are more then happy to tinker on your own ride. Hell… the e30 will probably enable you to learn enough handy knowledge to where people will start asking you for advise.
Bmw was here to help from the beginning, all e30′s if non-manipulate should have a basic tool set on the inside of the trunk:
All tools were made by Heyco and stamped BMW. Contents where 17/19mm wrench, 12/13mm wrench, 8/10mm wrench, pliers, allen key, screw driver with reversible blade (Philips and flat head), Spark plug tool, and a plastic manual window crank in case your window motor failed.
Some are also said to come with washers:
Bigger bmw’s had bigger tool sets as seen here:
For basic not to expensive tools i recommend Stanley, usually get a 3/8 and 1/4 short and deep socket set for $100.
If you want something main stream and really nice get: Snap-on, Mac tools, or Matco.
If you want to be cool and hip you want Hazet everything:
or you want to look like you know your shit get: hazet ratchets, Stahlwille wrenches, PB Swiss or wera screw drivers, and Knipex Pliers
At some point i think every do-it-yourself-er realizes he needs a vise, and although it might be temping to go out and buy a $100 new vise from retail locations I advise AGAINST that and finding someone (preferably locally) who sells used industrial grade vises. These are not only made better but are bigger, stronger, and will last longer then you will.
This is my new vise I picked up its a Rigid F-60, but dont limit your selection there have a look here:
