Questions this answer covers

Does Mazda CX-30 fit under €40,000?
Yes. At €31,000 it leaves €9,000 of headroom, and the budget was treated as a hard ceiling — nothing above it was allowed to win.
How does it cope with motorway miles?
On the measures that matter for motorway miles it scores 76/100 against a field average of 65/100, with 900 km between stops and running costs of about €200/mo a month.
Why a petrol car?
The question fixed the fuel, so only petrol car models were eligible — Mazda CX-30 is the one that scored highest among them.
