pulley and header fitment 3.0/3.2

So Im still on the fence if i should invest more money into this car or just save and re up on a 2003 6spd cls.. or maybe 2009 accord 6spd..

However i really cant wait and want to get ur pulley and or headers for my 3.0
I know the headers are interchangeable for the 3.0 and 3.2 if i get the 6spd one off the bat.. but what about the ur pulley is that interchangeable between the two motors?

If so I can get both headers and pulleys and switch em to the new car once I buy it..


2nd question what car do you think is better.. performance wise, 2003 cls 6spd or 2009 accord 6spd v6..

Thanks
