[S-mk3-B]

Wsup and nice to hear that you got your hands on a Turbo MK3! But first off, what's the condition if your car? How many miles does it have? Are there any kinds if leaks or anything unusual? The one thing that I always have to check are error codes. You should check to see if there are any codes stored up cause that will definitely give you an idea if there's anything wrong.
But as for basic maintenance like oil change, coolant change, brakes, etc... Is fairly easy with the the use of a basic tool set. And you can get a lot of help on maintenance from http://www.cygnusx1.net/Supra/Library/TSRM/MK3/
