There is a discrepancy between this page and the page covering the M103 engine. This page says that the early 1988-1993 300SL came with a 228BHP engine. This I believe is only true of the 300SL-24. The 300SL, of which some 12,200 were made only had the single cam 12v motor. The page covering M103 engine suggests that this engine has only some 170 odd BHP which I believe is true of its earliest days whereas I believe in its final form it has 217BHP. Further research is needed on both these pages.

The problems that I have pointed out with this page and the M103 engine page may be to do with this engine not having been available in the US. This needs correcting

When did the 320SL first come out?[edit]

It says 1994 in the article but I have seen 320 SL's for sale that claim to be as old as 1991. For example, this one - it's not a great photo, but it definitely looks like a 320SL to me. Could it really be 1991? thanks --Brian Fenton (talk) 16:22, 10 January 2008 (UTC) (talk) 21:54, 16 December 2009 (UTC) A book I have on the R129 (ISBN 3893653651) lists the 12V M103 engine at 190PS or 187bhp and the 24V version which was actually called the M104 as 231PS or 227bhp. I have seen lower ratings for the M104 engine when installed in different cars which could be down to the routing and size of any inlet and exhaust piping. It is also possible that the state of tune of the engine may have been altered to suit the character of the car i.e. sacrifice some top end power for a boost in torque for saloon and vice versa for a sports car.

To my knowledge the 320SL and 280SL , which replaced the 3.0 and 3.0 24v didn't come out until 1994. The increase in capacity I suspect was to try and give the 24V engine a bit more torque at low rpms as most road tests report that the engine felt lack lustre low down in te rev range I think that the 1991 320Sl is definitely a mistake.

The M104 was then replaced in 1998 by the V6 M112 which offered better economy, more low end torque and was lighter. This was a modular engine and by adding two cyclinders they made the 5.0L M113 V8.

Roadster vs. convertible[edit]

Can we agree this, being a two door, two seater car with folding top is a roadster? --Cloverleaf II (talk) 17:00, 29 December 2013 (UTC)

How can one tell a true AMG?[edit]

I've looked at quite a few R192 (500SL's and SL500's) and many have the rear AMG badge, but how does one tell if it is a true AMG? — Preceding unsigned comment added by (talk) 18:48, 19 April 2014 (UTC)
