The VAUXHALL ASTRA GTC (2011-18) 3DR HATCHBACK 1.7 CDTI ECOFLEX DPF SS 130 EU5 SRI 6SPD is a sporty, three-door diesel hatchback, giving the Astra practicality a sleek, distinctive look. It sits between family hatchbacks and coupé-style alternatives, appealing to drivers who want something individual without a premium-brand price tag. The 1.7-litre engine is suited to commuting and longer journeys, while the six-speed gearbox and efficient Ecoflex set-up make it a choice for keeping running costs in check. Its three-door layout and sportier character suit singles, couples or small households; families needing easy rear-seat access may prefer a five-door rival.
