I think you will find the '90 420 nicer ... The seats and doorpanels have different stitching (more up to date), and the radio will be also vastly improved as they have a 10 speaker set up. In general I find that the newer 126's are much more refined than you would expect in 5 years. (ie 85 vs. 90)

I'm looking forward to hear about the 90 SEL...

(Good luck!)
