I've had a 06 Zed and a 07 Zed,
The first was a Revup and the second is a HR.
Loved both, the HR was more my bag though.
Tax was high on both but you factor it in to the enjoyment and budget it every year.
They are beautiful cars, Comfortable but fairly nimble.
Budget for your first year for the below
Tyres (MPSS)
Brakes (Discs and Pads)
Exhaust
High Flow Cats
Wheel Refurb
Because you will replace them.
The stock exhaust is depressing (Really depressing!)
Brakes... Get something meaty!
Tyres, MPSS are awesome and every zed should have them
Wheel refurb, I'm yet to find a zed with a standard wheel paint that doesn't need them.
You'll enjoy every minute
