And, some clarification on donor options would be great...
SL500, 2002/3 through 2008 for sure.
What about SL55 AMG, SL600 or SL65 AMG from same period?
And, how about the facelift versions from 2009-2011/2..? Wee they exterior changes only so would still work or no..? If they are good still, then that also opens up SL500 or SL63 AMG as options.
Unsure if UK had all those options, but SL55 AMG is a supercharged V8, and SL600 is twin turbo V12, both offering 493hp. SL65 AMG went to 604hp. SL63 AMG around 518hp. All significantly more than the 300hp or so of the SL500.
