According to
http://www.cars101.com/subaru_svx.html the Touring Package on a 92 included:
- Leather package: seating surfaces, steering wheel, shift lever, parking brake handle
- Power drivers's seat, 8 way
- Power sunroof
- Electronic vehicle speed sensitive power assisted rack and pinion instead of engine sensitive. Vehicle speed sensitive is much more accurate and responsive for precise driving.
- Stereo: 6 speaker, AM/FM/Cassette/CD
- Heated outside mirrors
Block heater and rear deck spoiler were listed as Optional components for both models, and CD Player was optional for the non-touring.
Hope that helps!
