OPO (Porto Francisco Sá Carneiro Airport - Portugal)
Platinum
Booked: IDMR (1 Series)
Received: SDMR (Opel Insignia - 3 Series equivalent in size)

A fine upgrade; up until now, had no luck with real group upgrades (edit: IN PORTUGAL, elsewhere it is common practice), but I was very pleased this time.

The Insignia is a very underrated car in my opinion; it is not extremely comfortable in bumpy roads (harsh shocks), but otherwise has plenty of space, handles great in motorways, has a very good mileage and in my hands, it just felt great and I just love the overall styling.

Very pleased (yet again) with my experience with SIXT.
