I have #240 built on 4/12/97 (IIRC) from the OASIS printout.
I replace my water pump at about 80,000 miles as preventive maintenance. It had the white impeller so it already had the improved better impeller. It also had a loose baffle plate. I don't know when that issue was resolved. I replaced it with a factory pump assembly and it lasted until about 235,000 miles when the front seal started to leak.
Build numbers started over with each model year. E0 and E1 ran together as they were both the 98 model year.
I don't believe the E0 had any more problems than the later years, and the later years were decontented a little each new iteration. Also, I prefer T-Red with Midnight Blue interior to T-Red with Saddle Tan interior.
