I once pulled a pair of 2000 Regal seats from the junkyard, and put them in my GTP. Night and day difference. I had back pain issues from the GTP seats and never even knew it (figured it was my job, being on my feet all day, bed was too soft, etc...). Pain went away after using the Regal seats for awhile. The trips between Michigan and Tennessee were infinitely more comfortable. Go for the upgrade!!
