Mercedes SL 65 AMG
Why 3.0: A 1,000 Nm V12 that no chassis engineer was consulted about. Toll-booth sprints, then valet parking.

Sound
Twelve cylinders and two turbochargers produce a deep, distant murmur that never raises its voice. Mercedes tuned this for effortlessness, so the turbos absorb the induction noise and the 6,300 rpm limit arrives before anything has begun. Torque you feel rather than hear.

Child seats · ISOFIX
There aren't any — strict two-seater.
No ISOFIX on the front passenger seat. Shares the R230 SL's AKSE system — a Mercedes-approved child seat is seatbelt-mounted and recognized by transponder, switching the airbag off automatically.
What looks like a rear bench is a parcel shelf — no child restraint is legal back there.

The long version
Twelve cylinders and a torque figure built for bragging rights, in a car whose owners mostly deploy it in the fifty yards between a valet stand and a restaurant awning. Values cratered by more than 40 percent in the years after launch and have only recently climbed back, tracking a used-market buyer who wants the V12 badge at a fraction of new-car money and drives accordingly little. Valet Royalty is the honest read: this is a car selected for the sound it makes idling outside a hotel, not for anything that happens on the way there.
