Bristol Airport - SIXT Platinum through BWR status match
Booked: Sedan (IDMR) - e.g. Skoda Octavia
Received: Peugeot 2008 (CFMR)

Upon arrival at the desk, I was offered an Audi A1 or Peugeot 3008 both for 50€ extra, or a 2008.
Asked for the Platinum upgrade but was refused. Emailed the loyalty program who confirmed I am entitled to the upgrade.

Took the 2008 not realising it was a downgrade (awful car by the way) and it was the only vehicle offered that didn't require extra payment. Looked at what category the 2008 was in and was having issues with the android auto upon arrival to my destination.

Ended up phoning the station to complain about being downgraded to a smaller car and was offered to switch the car the following day to either, a C5 Aircross auto (IFAR) or a BMW 1 Series Auto (ILAR) after the agent tried to convince my the CFMR was an upgrade to the IDMR... Took the 1 Series
Not the best experience overall.
