Legend_101,
I just bought my wheels a few months ago. The Enkei RS-6 17" were also on the top of my list. The other one I was considering were the Enkei RS-5 17", which I went with.
I saw a 92 Legend in Manhattan right before I bought my rims with 18" (looked a little larger than mine) RS-6's and the offset was pretty obvious. I was glad I didn't get them. Right now, my RS-5's are pretty much flush with the side fenders and have a very clean look to it.
So depending on how you like your wheels to look on your car (ie jutting out a little or flush with the fenders) you can take your pick. I personally recommend the RS-5's, but that's just my taste.
Hope this helps.
