Alfa Romeo Giulia Quadrifoglio
Why 7.8: Nobody cross-shops a Quadrifoglio — you either get it or you buy the German one. The people who get it drive it hard and keep it long, depreciation be damned.

Sound
The 2.9 twin-turbo six is hard and metallic and genuinely revs to 7,300, further than any rival super-saloon engine, and the exhaust cracks properly on the overrun. But two turbochargers still stand between you and the induction, and there is a Busso in the family history.
6-cylinder · turbocharged · 7,300 rpm redline · rated 7.3 / 10 for engine sound
Market value
Median asking price, good condition · €63k (2018) → €40k (2026), trending down · illustrative data
Child seats · ISOFIX
Both rear outboard seats have standard ISOFIX, verified via Euro NCAP's 2016 child-occupant testing.
No ISOFIX at the front passenger position — inferred from the Stelvio's Euro NCAP datasheet, since Giulia and Stelvio share the same 'Giorgio' platform and cabin architecture; Giulia's own datasheet wasn't directly accessible to confirm independently.
A front-passenger airbag cut-off switch is standard on the Stelvio; treat as likely-but-unconfirmed on Giulia given the shared platform.

The long version
Alfa's reliability reputation does some of the buyer-screening work before the car even gets bought; anyone put off by the idea of Italian electronics has already self-selected out, leaving an ownership base that is genuinely committed rather than accidental. Values have fallen more than a third since 2018, and the used buyers arriving through that Bargain Window tend to be the same type as the original owners: people who wanted the Ferrari-derived V6 badge more than resale security. It shows up in the mileage data too, high use, low flip rate, because nobody buying a used Quadrifoglio at a discount is doing it to park it.
