New VW Golf GTD: Price from £25,285

At £25,285 the new Golf GTD – revealed at the Geneva Motor Show last month – is just £310 more than the old model despite an increase in equipment and performance and a better specification. Looking pretty much how you’d expect a GTI Diesel to look, the GTD gets smoked LED rear lights, bi-xenons with LED running lights, two chrome tailpipes, 18″ Nogaro alloys and the slightly butch body kt which includes side skirts, butch bumpers and a roof spoiler. Inside is ‘GTI’ too with tartan trim, black roof lining, sports steering wheel and GTD-specific trim for the gear lever, trim strips and instrument cluster.
