Mercedes-AMG GT R
Why 4.8: AMG's most serious road car — rear steer, nine-way traction, a Nordschleife record at launch. Half get tracked as intended; the green ones increasingly live under covers as the last pre-hybrid AMG halo.

Sound
The same 4.0 twin-turbo V8, but dry-sumped, closer to your back and running a far angrier exhaust that bangs on lift. It is still boosted, so 7,000 rpm arrives flat rather than climbing. The best of the modern AMG V8s, still short of the older NA ones.
8-cylinder · turbocharged · 7,000 rpm redline · rated 7.6 / 10 for engine sound
Market value
Median asking price, good condition · €138k (2018) → €152k (2026), trending up · illustrative data
Child seats · ISOFIX
There aren't any — strict two-seater.
No ISOFIX rails. Shares the C190 GT's AMG sport bucket seats and automatic child-seat recognition — an approved seat is detected by transponder and the airbag disables itself.

The long version
AMG built this to embarrass Porsche at the Ring, and the buyers who cross-shopped it against a GT3 back then still take it to track days now, running the nine-way traction control through its full range instead of leaving it in Comfort. The rest arrived later, once being the final analog-feeling AMG halo became a marketing hook worth paying for, and that crowd treats the car more like a hedge than a hobby. Running costs on a hand-built biturbo V8 do some natural filtering either way — nobody keeps one they don't intend to actually start.
