Here mate, well the 120 is nice, absolutely fine everyday useable power - nice torque low down - and good fuel economy, cheap insurance, pretty reliable and cheap to repair. Buttt the 180 is calling me after a year or so of 120 ownership as I want to hear that v6 noise everytime I floor it! (even though i'm sure my bank account will hate me for it hahaha)
Forgot to mention it also has a custom made backbox which looks great and sounds fantastic, really subtle when cruising, not too much louder than standard and not droney on the motorway, but in town give it a few revs and it sounds great! Really sporty, will def go back to the same place and get another made exactly the same for my next ZS
