Actually cheaper than buying the points and getting it off the R3E store for me. Less than 5UKP on Steam. vRP cost at least 6UKP per 1,000 (if you pay in €) and the DTM13 cars alone cost 1,000vRP in R3E store. Edit2: Apparently, all I had to do to 'register' the purchase with S3 was start the game in Steam and it linked the two accounts and told S3 that I own it now - fixed. Nice and easy.
