In the market for a W140 and wondering what (if any) were the last years for the evaporator core issues and engine wiring harness issues? I was told that the later models were much more reliable. I was also told that by 1995-96 that MB stopped using the biodegradable wiring harnesses on the W140... is this true? I was also told that the later W140s (from 96-on) also had a much more reliable evaporator core. True?

I found two W140s that I like. One is a 96' S420 and the other is a 97' S320. The S420 has a new transmission and blower motor listed as two major repairs. It has 125K. The major concern with this one is that it is in California and I am in Tennessee. Shipping will be $$$$! I can get the car for about $4500.

The 97' S320 has nearly 260K, but stated to work perfectly in everyway. It near Washington DC... not as nearly as far as the S420. I can probably get this one for around $4K. I am not looking for a show car... just something to drive around town and on trips.

Thanks.
