Porsche Boxster Spyder (981)
Why 6.3: A 3.8-liter flat-six shared with the Cayman GT4, a manual-only gearbox, and a fabric top folded by hand instead of a button — Porsche's purest recent argument for a roadster. Low production numbers mean most surviving cars are already in enthusiast hands rather than dealer inventory.

Sound
The Carrera S 3.8 flat-six with no roof between it and your ears, revving to 7,800 with the hard mechanical rasp only an unturbocharged Porsche six makes. It is a road-car engine rather than a motorsport unit, which caps it below the 9,000 rpm cars.
6-cylinder · naturally aspirated · 7,800 rpm redline · rated 8.4 / 10 for engine sound
Market value
Median asking price, good condition · €75k (2015) → €110k (2026), trending up · illustrative data
Child seats · ISOFIX
There aren't any — strict two-seater.
The front-passenger ISOFIX/airbag-switch option carries over from the regular 981 range. The Spyder's standard folding sport buckets aren't the fixed full-bucket type Porsche excludes from child-seat use — the optional 918-style lightweight buckets would be.

The long version
Porsche built the Spyder as the Boxster nobody was demanding, and almost nobody who understood it walked away: a manual-only flat-six roadster with a soft top that folds by hand, sharing its engine with the Cayman GT4 that got all the attention instead. Because it never got a PDK option and never chased a lap-time headline, the buyer pool skews toward people who specifically wanted the mechanical simplicity over the wing, and that shows in how the surviving cars get used, driven hard with the top down rather than trailered. Values dipped briefly after production ended before climbing again as manual-only Porsches got scarcer everywhere else in the range.
