Yep, up to 87 is the S1 Pinny looking front end but trust me, many have had these changed (like mine) so best to ask.
Manuals are hard to come by but do exist so look out for a manual would be better and make sure it has an LSD diff (if its important to you) as not all do. I had to change mine from single to LSD but was factory manual. Also bear in mind, wheels are hard to get in the offset with 4 stud.
Also look for one with an RB20DET ECCS, many has NICS engines and even RB20ET's etc.
Other than that they are a great car, I love mine and as they are different they attract a lot of attention. Everyone told me to get a 32, wanted something different and haven't regretted it for a day.
