Don't be jealous

Everybody has it's own way gathering info on the product the intend to buy, to minimise risk. For instance - you said that your goal for buying Mazda was good MPG. But, how you can expect that from non-turbo petrol engine and electric drivetrain mounted before gearbox to be efficient? It is simply not an efficient setup. On the other hand Volvo XC 60 has turbo engine (which is more efficient, but on expense on longevity) and EV drive directly connected to the rear axle (which is also more efficient, but on the expense of the AWD capability when driven EV). It is much more efficient setup, but comes with a price. And the difference in price will never be paid with better MPG from Volvo. If you want more MPG - then Mercedes GLC is for you they have diesel PHEV and advertised EV range over 100 kms. But that comes with the price too.
But, considering my way of gathering info - I would never buy a car which is a first model year. It is a unwritten rule that cars have much less problems later in the production of specific model. It goes for all manufacturers.
