Having taken out a nice 2003 2.5 Sport before buying our 3.0, my opinion is the the extra 40bhp is really noticeable, almost the same difference between the 3.0 and the 4.0 but without the extra weight of the V8. Not that the 2.5 is slow, but the 3.0 is actually quite fast! I held out for a 3.0 manual Sport, and I'm glad I did
Below are the results from using the clay if anyone is still interested. Hard for the glass like finish to show in silver especially in photos but up close looks like a mirror. If anyone else has good results share your photos. Cheers Bromers.
