Finally managed to get some pics of SDM’s R620 after many months of evading me. Enjoy 
Also saw this at the test centre, couldn’t get a decent pic but sounded immense
sweet! 
use to see it on the A36 in Salisbury heading Southampton bound
also saw it near Warminster one Sunday evening a few weeks ago
They’ve got the R620 an R560, an R580 and 2 105’s that i’ve seen although they do use a few subbies
that does look a nice piece of kit & not over the top with spots.
