Our chosen spec takes the upgrades found in the Ventura spec then adds a few extra details, such as leather seats, privacy glass, dual-zone automatic air conditioning and more. Thanks to all of the additional items, Ultimate spec helps to better align the Tivoli with even some of its more expensive rivals. Ultimate Nav upgrades the infotainment system to a larger 9.0in colour touchscreen and adds TomTom sat-nav to the mix. When you consider that Ultimate already offers smartphone mirroring, it’s likely that you won’t need that addition.
