The figures we list are without mirrors - the larger figure you usually see is with mirrors. Unfortunately this can be a grey area as there seems to be an equal divide among people who want figures with mirrors and those without. Our data is supplied by a company who use the smaller figure for consistency - other websites will sometimes quote one or the other but that's not always clear. The two figures we list for the Golf are for the three and five door models - 1779mm is the 3-door while 1786mm is the 5-door. Modern cars are certainly wider and have larger mirrors as a result, so if you have a narrow space it can be tricky to find a car that fits. Volkswagen don't give a width for the Golf with mirrors folded in their technical data - the only way to find out may be the traditional tape measure at a Volkswagen showroom!
