The cabin has dual-zone automatic climate control that senses whether the hardtop is open or closed and adjusts for sun position. Cruise control is standard with steering wheel controls. A 7-inch touchscreen handles the DVD navigation, climate and audio.
Boot space is 368 litres with the hardtop closed and run-flat tyres. It drops to 135 litres with the roof stowed.
Gross vehicle weight is 2110 kg and kerb weight around 1815 kg, giving a payload of 295 kg. Spec sheets list no towing capacity figures. The car is not set up for trailer work.
The cabin uses hand-stitched soft leather on seats and trim details with genuine wood accents on the console, doors, fascia and cupholder covers. Front seats offer eight- or ten-way power adjustment including lumbar support plus memory for two drivers and variable heating. Dual-zone automatic climate control includes a clean air filter, solar sensor and special lap-jet vents that direct warm air to the thighs when the roof is down. A wind deflector sits behind the rear seats and the Mark Levinson nine-speaker system automatically levels sound for roof-up or roof-down driving.

Official European figures list combined consumption at 24.8 mpg and CO2 at 269 g/km once the six-speed automatic replaced the earlier five-speed unit. Urban and extra-urban figures sit at 17.3 mpg and 32.8 mpg respectively. The 4.3-litre V8 meets Euro IV emissions standards.
Lexus schedules a health check every 10 000 miles or annually and a full service every 20 000–30 000 km or two years. Oil and filter changes fall due every 15 000 km or once a year. Iridium spark plugs last 60 000 miles and the timing belt needs replacement at roughly 90 000–100 000 miles together with the water pump.
Safety equipment is comprehensive for the period: dual-stage front airbags, front side airbags, ABS with electronic brakeforce distribution and brake assist, traction control and vehicle stability control. Front belts carry pretensioners and force limiters. the body incorporates extra bracing and reinforced A-pillars for convertible rollover protection. No official Euro NCAP result appears in public records.
Day-to-day ownership centres on regular oil changes, monitoring coolant levels to protect the head gasket and keeping the retractable hardtop mechanism clean and lubricated. Run-flat tyres were standard on early cars, removing the need for a spare and freeing boot space.
