There is an 'interesting' note in the description:

"A further bill on file is included from Blade Honda for a staggering £9,424 detailing a replacement factory Alpine stereo unit and replacement digital climate control unit in Nov 2018 at 11,480 miles which must have made the eyebrows raise a little!"

Ignoring the Alpine reference, which must be a typo as there is clearly a Bose head-unit in the car, how is an invoice of nearly £10k achievable for these two components?
