You may be surprised to learn that Adria built its first caravan way back in 1965. And now, 50 years and some half a million tourers later, the Slovenian firm is hanging out the bunting and chilling the bubbly in a public celebration of this not-inconsiderable achievement.

We’ve already reviewed one of the two ‘Silver Collection’ caravans Adria is producing for the 2016 season, the new Altea Eden, but there’s a bigger and more couple-oriented model in the line-up, too. And it’s based on the existing Isonzo.

Like the Eden, the Isonzo gets a serious makeover, with the stylish iShape body swathed in silver and kit levels ramped up with alloy wheels, a microwave oven and Alde heating. All very impressive, but surely that little lot’s going to ramp up the costs, too?

Not so. A standard Isonzo costs £18,390, so with the Silver Collection’s extra kit you might expect an RRP of around £22,600. In fact, it costs £19,390 – just £1000 more than a standard model.

The special edition also benefits from the new kitchen treatment all Adoras get for 2016, which includes a bigger fridge and a repositioned oven. And to see other Adria caravans for sale, click here.
