I'll be adding buying information on other models of Probe as I get more information. The first installment of this page will focus on the 2nd gen GT.
1995 may be overall the best year. Virtually all of the bugs in the earlier years were worked out and the emissions system is pre OBD-II. ODB-I systems in the 93-94 are simpler to work around for performance enhancements.
1993 is the lightest year primarily due to having only one airbag. On the other hand if you want two airbags you are looking for a 94-97 model.
1993 and earlier 1994 models of the 2.5V6 can have problems with carbon knock. A redesigned head in mid 1994 (roughly March 1994) solved this problem.
1993 to 1994 and early 1995 (built before Jan/Feb 95) can suffer from rear caliper lockup. Redesigned calipers in 1995 solved this problem.
1993 and 1994 may also suffer from intermittant distributor failure.
Note that I have a 1994 PGT and have not experienced any of the problems specific to the 1993 or 1994 models. - James
All 93-97 PGTs may suffer from leaking valve covers gaskets and premature failure of battery.

Lowest part of rear bumper molding a little different. The 1994 GT (and all subsequent Probe GTs) has 164HP @ 5600rpm, 160 ft/lbs torque @ 4800rpm.
Base - Several stylistic changes from 1994 as follows: Tail lights are restyled, but plate still between the tail lights. Interior doors panels restyled. The interior door handles are now just handles instead of being convenient places to keep some change like in the 93 and 94.
SE - No changes from 1994 except as listed above in the 1995 Base.
GT - Same interior changes as Base '95 and SE. Vestigial stripe remaining from pre-dual air bag 1993 model now disappears completely. License plate has been moved from between restyled tail lights down to lower bumper area. A large plastic GT logo now resides between tail lights. The rear valance was changed in 95, omitting the full-width "vent" under the bumper. The replacement vent is shorter, and the valance sweeps up on either side. Taillights trimmed in red. The small GT sticker next to the metal PROBE badge under the left tail light has been replaced by a metal 24V badge. The 16" 5 spoke alloys have been restyled from straight spokes to "sweeping" spokes.
Check out the window sticker from a 95 PGT Here.
