It seems like many people on this site don't know too much about the years, generations, and facelifts of the Toyota Camry. I know quite a bit about the Camry however, since it is one of my favorite cars and I have done lots of research about it.
It's really pretty simple actually. Except for the very first generation of Camrys, Toyota follows a strict set of guidelines for the generations and facelifts of Camrys (as it also does with Corollas). Camrys get a full redesign every 5 model years (ex. 1992-1996) and get a facelift for the last 2 model years of each generation (ex. 1995-1996). The trouble is knowing which is which, and I hope this will help some of you with that.
First Generation: 1983-1986
1983-1984 Camry
For 1985-1986 Camrys got new flush headlights along with a new grill
Second Generation: 1987-1991
The Camry was redesigned with new more rounded sheetmetal for 1987
For 1990-1991 Camrys got a new grill with Toyota's new logo, new taillight lenses with the amber turn signals now on the bottom, and
new body colored doorhandles
Third Generation: 1992-1996
Camrys were redesigned for 1992 with a completely new, much more aerodynamic look
For 1995-1996 Camrys got new rounder headlights, and a body colored plastic piece between the taillights instead of the full-width treatment they had before
Fourth Generation: 1997-2001
Camrys were redesigned in 1997 with a slight more refined look than the previous generation
For 2000-2001 Camrys got new transparent headlights, a new grill, and new crystal taillights that were slighty larger
Fifth Generation: 2002-2006
The Camry was redesigned for 2002 with much more radical and angular styling
