Jaguar XKR-S
Why 5.8: DougScore 56 for Jaguar's angriest XK, the widebody send-off before the F-Type took over the whole range. Depreciation has been steep enough that it now undercuts the car that replaced it, despite being faster.

Sound
The active exhaust on the supercharged 5.0 opens earlier and crackles harder than the F-Type's, and it is the angriest noise Jaguar has signed off. But the drama is a valve opening rather than an engine breathing, and blower whine sits over everything.

Child seats · ISOFIX
X150-generation rear ISOFIX anchors are present, but the deeply bucketed rear seats mean only compact Group 1 seats really fit — a recurring owner complaint.
No ISOFIX — any front child seat would be seatbelt-mounted only, as on the rest of the range.

The long version
The XKR-S was Jaguar's send-off for the XK generation, a widebody, stiffened, more aggressive final word before the F-Type took over the range entirely — more power, a locking rear diff, and a chassis wound tighter than the standard XKR without ever feeling as sharp as its numbers suggest. That timing worked against resale: buyers cross-shopping used sports GTs increasingly wanted the newer, more talked-about F-Type, leaving the XKR-S to depreciate as an overlooked stepping stone between two more famous cars. What's left is a genuinely quick supercharged V8 GT that gets bought by people who did the math and realized it undercuts an F-Type R on price for more power, then driven the way any big, cossetted coupe gets driven — warm-weather roads, not warm-up laps.
