Not the case -- there is no reversal of the burden of proof for
Distance Selling Regs, so the burden of proof here lies with the buyer
It's different for the purposes of the Sale of Goods Act, where the
burden of proof lies with a party who claims that the other party is
not 'dealing as a consumer' (by s.12 of the Unfair Contract Terms

There is no SI on cars (at least in relation to whether the seller is
a 'supplier' for the purposes of the Distance Selling Regulations).
Maybe you're thinking of Blakemore v Bellamy, where the defendant was
found to be a 'hobbyist'. I can't remember the exact number of cars
or the time period, but the appeal Court upheld the decision at first
instance, albeit in a rather disapproving tone.
