There's a curious issue inasmuch as when looking over it today I found that the inside of the fuel door was filthy, whereas the rest of the car was spotless. On cleaning the inside of the door I found the tyre pressure recommendations which were for 18" wheels. However, as part of the docs I have receipts for tyres going back to early 2013 which (like the wheels) are 17" :frown:.
Your Data Card info confirms that 18" AMG's were fitted in production, so some crafty previous owner/dealer has done a swap :crying:
Fortunately it seems to have all the other features it was built with,although taking out the heated seats or parking sensors wouldn't be a five minute job :grin:
