My S1 YLW was £499. The basic pricing is anything with 1 number plus random letters (usually people's initials) is up to £499, anything with 2 numbers plus 'initials' is up to £399. I did a lot of research to work out what I could get for the smallest sum of money that would not mean much to the price setters but fit the car. My Mrs has W12 VRS on her Octavia vRS (her nickname is Wiz) - that was £399 which surprised me, I thought they would hike the price for the VRS meaning something to Skoda owners!
If the 3 letters spell stuff obviously the price goes up (potentially a lot!), but £3000 for AWD sounds way too much, I would have said £999 max.
