Replace The Discovery Sonia Edition

You asked whether a Discovery 4 might be good, having heard they are far less reliable than the Disco 3. The received wisdom is almost exactly backwards, with one enormous asterisk.

The D4 is a better-sorted car than the D3 — the most reliable Discovery of all is the D4 with the late 2.7 TDV6. But from 2011 the D4 went 3.0-only, and the 3.0 TDV6/SDV6 has a crankshaft failure mode the 2.7 never had (acknowledged in TSB LTB00487). When it goes, the engine is scrap: £4,500–£7,500.

Why it's academic anyway: a manual D4 exists only on the early 2.7 (2009–2010) and is genuinely rare; there is no petrol Discovery; every diesel Discovery has a DPF and the school run is the classic DPF killer; and VED runs £445–£760/yr. The honest answer to "Discovery 4?" is no — not because it's less reliable than your D3, but because it's diesel-only, auto-only in practice, DPF-equipped, and taxed heavily, being bought for exactly the duty cycle that kills modern diesels.

Petrol ~150p/litre; diesel ~165–167p/litre. At ~6,000 miles/year the petrol-vs-diesel fuel-cost gap is roughly a takeaway per month — swamped by the DPF/short-trip problem, higher diesel servicing and softening diesel resale. Petrol or a full petrol hybrid is the only sensible answer.

VED 2026/27: post-April-2017 registrations pay a flat £200/yr. Pre-2017 cars pay by CO₂ — the bands that bite here are H (166–175 g/km) £325, J (186–200) £410, K (201–225) £445, L (226–255) £760. Old petrol SUVs sit in H–J; old diesel Discoverys sit in L.

A realistic two-Labrador setup needs a boot floor of roughly 100 cm wide × 75–90 cm deep × 70 cm+ tall — one XXL crate, a twin-compartment estate crate (Barjo, Lintran), or two 30–36in crates side by side. Rule of thumb: under ~450 L seats-up is marginal; 500 L+ with a flat floor and square aperture is comfortable.

Estates counter-intuitively compete with SUVs: lower load lip (kinder to ageing Labradors' joints), longer floor, but less height — a tall crate may need the parcel shelf permanently out. Take the crate (or its footprint on cardboard) to every viewing. Litre figures lie; tape measures don't.

1. Manual non-negotiable → Honda CR-V Mk4 2.0, Škoda Kodiaq 1.5 TSI 5-seat, Mazda CX-5, Sportage Mk5 with warranty, or a new Bigster. All petrol, all crate-friendly, all school-run-proof. There is no manual Land Rover answer and no manual hybrid answer — they don't exist.
2. Manual negotiable → Toyota RAV4 Hybrid or Honda CR-V Hybrid. Objectively the best drivetrains for the low-mileage school run. Test-drive first; town hybrids don't feel like slushboxes.
3. It must be a Land Rover → Discovery Sport P200 petrol (auto).

One honest note: the manual being given up was attached to 2.7 litres of diesel V6. A 1.5 TSI or 2.0 i-VTEC manual is a lighter, snickier thing — the preference may survive the transition better than expected.
