SL/R230: differences between 2003 and 2004 SL500
Major equipment change was the 7 speed transmission, which makes the car feel much more lively.
For me, the differences are night and day. I wouldn't own the 2003 and I love the 2004.
But I surely hope you didn't sell the 55 for a 500
Mb guy, from what I know there will also be a new sound system for 05, aswell as as new colour, some sort of black for nappa seats or something minor. I'd probably just wait for the 05.
I sold my SL55 because I was having problems with it as well and wanted something produced later. I thought about the SL600 but when I drove it, I thought it was lethargic and wound up with the SL500 as a stopgap until I can drive the SL65.
