checked it out,iv been told 'lambo' yellow is just another basic yellow colour used on the colour charts, a standard 2pack paint.not really special to the average joe.
joe bloggs walks down the street and sees a lambo yellow cupra,he wont really notice the difference compared to onvi yellow.the only people who would probly notice it is of course us,the seat enthusiasts.
so iv ruled out lambo yellow a while back.and orange because i would have to inform the dvla,and insurance would want to know etc.so which leaves liquid yellow which is noticably different to onvi yellow methinks.
