im not sure about the mondoe unit, but the granada 24v is a peice of piss to install it uses the sierra mounts, only the electronics can be fiddly and in my opinion it looks better. but if u do manage to install the mondy unit id love to see.

my neigbour has a red st220 and it seems to do the job, although it dosent sound as good as my 24v cos, and it dosent seem as quick, i know its meant to be 220bhp but on the motorway it cant keep up with the cos
