the look of an R33 sedan and coupe is too different, the sedan looks more like a latemodel camry and really conservative in the looks department.
They even changed the tail lights! thats what make a skyline look good
the r32 and r34 sedans pretty much look like their coupe counterparts except with 4 doors,
i would go for a 4 door R32 or R34, stay away from the R33 sedans, and plus the manual R33 GTST sedans are extremely rare, the ones ive seen are all auto.
