I am looking at a 1993 400SEL thats at a dealer lot.

Was 1993 the only years for these? I was told they were only made a couple of years, so I was wondering if they had wretched engines which was why they were discontinued. According to KBB, 1993 was the only year and I want to know why.

I know the basic W140 issues, but wondering about that 4.0L engine. Are they good engines and basically as reliable as the 4.2L? Parts hard to find for that engine?

Thanks.
