There's lot of interest in motorsport in Norn Irn, both 2 wheels and 4. Rallying and road racing in particular. That translates into what people buy for themselves and, being canny, no surprise that many gravitate towards performance VWs and Audis. There are a fair few beemers knocking about as well. With house prices in NI being some of the lowest in the UK, folk generally spend more on their cars than in other areas.
