Which Volvo B10M is your favourite? 
MK1 (SBS9C)
MK2
MK3
MK4 DM
MK4 Strider
MK4 DM3500
For me, MK2. Very nice ZF
'cat' sound, especially DM ones. WA ones look fierce and
classic. 
Always took them
on 82, miss them so much... 
I've never taken SBS9C.
MK2s are good! I like the NAC feel.
MK3s not bad, nice voith but my fav is SBS877M
MK4 DMs are good, nice ZF.
MK4 Striders are better than DMs, ZF sounds nicer, but noisier
if heard from the outside.
MK4 DM3500 is totally the best! But the aircon is
freeeeeeeeeezing... Much colder than the OC500LEs.
