The GT LWB Rifter is the longer MPV variant (L2) with a sharper-trimmed interior and exterior; on the 2026 model range the common diesel is the 1.5 BlueHDi paired with an 8-speed automatic (EAT8). Diesel automatics reward steady, higher-mileage use — they are efficient on motorways but you should be mindful of DPF/AdBlue servicing and the automatic's scheduled fluid/software service intervals. Confirm whether the LWB car has the optional third row (some LWB examples are 5-seat; 7-seat is usually an extra) and check ISOFIX and access if you need seven seats.

• DPF and AdBlue: ask where the AdBlue filler is, confirm AdBlue level/status, and verify dealer has carried out any required initial DPF regenerations (diesel cars used only for short-yard moves can clog a DPF).
• Automatic gearbox behaviour and history: check for smooth shifts cold and hot, ask for any gearbox software updates, and confirm the manufacturer's EAT8 fluid/service intervals are noted in the handover paperwork.
• Seating configuration and fittings: confirm whether this LWB is fitted as a 5‑seat or 7‑seat, test third-row mounting/folding and ISOFIX anchor access if you need child seats.
• Sliding doors and seals: inspect both sliding-door runners for smooth operation and check rubber seals and door alignment on the longer body for squeaks or binding.
• Infotainment and ADAS: check touchscreen, Apple/Android mirroring, reversing camera and parking sensors, and that lane‑assist / autonomous braking systems are functioning and not showing fault warnings.
