Good luck with the new to you car.
If you plan to do a lot of work on the car yourself, then you'll find three things really valuable:
- Durametic diagnostic tool - (versions 6 or 5)
- Bentley service manual
- 101 Projects book
You can find all of these things new or used on the web. The Durametric allows you to read diagnostic codes, test systems, and reset things like the CEL and airbag warning lights.
