Thanks for your input Chris. I'll keep the warranty. I noticed some vibrations from the seats when I go more than 60 miles on a freeway. Mostly when I am accelerating and it doesn't feel right. I don't feel the same vibrations through the steering wheel though. Also, steering wheel is not perfectly straight, could this be a reason? Do I need an alignment? Again, mine is 91 legend LS with 110K miles on it.
