Verdict · NHTSA data
Limited data — recalls on file
NHTSA has just 20 complaints on file for the 1993 Audi 100 — too few to judge reliability from owner reports alone — but 3 recall campaigns apply to this year, so any used example should have its VIN checked for completed recall work.

The record is thin — 20 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 3 recalls should be verified as completed.
According to NHTSA complaint data, the leading problem areas are fuel system (8 complaints), engine (6 complaints), speed control (2 complaints).
