I read a number of posts on this prior to buying my 3.7 Roadster (it very nearly put me off this particular model) yet I do not seem to have any issues.
Admittedly, I do not feel the need to push the car that hard, it cruises very nicely at low revs but when I do push a little harder before shifting up, I see the revs drop as soon as I come off the accelerator and depress the clutch.
If anyone has ever captured on video their rev counter (by a passenger hopefully) showing this characteristic, I'd really like to see it.
Cheers
Steve
