I'm not sure I get the dig at SEAT here? in my 18 years of driving I have had 12 cars of all different brands, mostly premium brands and not one of them has had 2 reverse lights? I can't even think of a single car which does?
I've had 6 different cars and this and my pre facelift Leon are the only ones with 1 reverse light. I've had a clio, 3 fiats a corsa and my mk5 Astra all had 2 reverse lights as well as my Mrs fiesta and kuga. I'm sure most cars do tbh.
