Correct. And from 1998-up, the SL320 was not sold in the USA, only the SL500 and SL600. Overseas, the SL320 from approx 1999-up did indeed get the M112 6-cyl, but that was never sold in the USA.
The M104 engine in the SL320 is a DOHC, inline-6, 24-valve engine. The 90-93 300SL got the M104.981 engine. :) -dm > ------------------------------ > Date: Fri, 24 Mar 2006 09:45:55 -0500 > From: "James Zavesky" <[EMAIL PROTECTED]> > Subject: Re: [MBZ] An SL for wifey? > > > The SL320 ( 129.063 ) used the 104.991 engine which is an inline 6 produced > from 1994 to 1997. > > James Zavesky
