Well it's finally come through.
Paid £299 for a Personal Service Plan from Mazda UK for 36 month cover.
Services at 12500, 25000 & 37500.
On the plan it states a total cost of £649, so less than half the normal cost.
Got the impression dealerships don't push this and most customers are blissfully unaware of it.
So anyone buying a new CX-5 do yourself a favour and take a look into this.
Just for info, when I phoned the dealership for a price for the first service I was quoted £195
