Yes, just be wary about what's included in major/minor service as I've had lots of arguments with main dealers about getting spark plugs included for a Hybrid I service (assuming thats a minor service). The website says its included but my dealer says its not.

Just checked, in Edinburgh UK a 2015 registered i8, hybrid I is £257 inc VAT and a Hybrid II is £1025. (You'd think the prices would be the same Nationally except London - odd - unless newer car owners are getting ripped off)
The only apparent difference between them is Hybrid II includes struts & belts. Both include (all 3!) spark plugs.
Your deal appears to be for 2x Hybrid I +£54 brake fluid+ a free£45 MOT...so still a saving.
