Back in the day, Subaru, Toyota, Mitsubishi, Audi, Lancia and Nissan all had their loyal fans thanks to homoglomation of certain cars. Probably due to no Playstation and the like. That created a subculture from the group-B rally days of 600hp 4-pot monsters. After, as said, it transformed into fans from computer games as already mentioned. I for one was that person. Spending evenings with the curtains closed and the TV and Playstation on in my bedroom playing GT and N for S. It certainly introduced me to certain cars like the ones already mentioned. Both are reasons why some cars will go up in value. Just a cult following of like minded people who have a nostalgic view of certain cars they couldn't afford at the time but can now.
As some of you know, i recently bought a Pulsar Gti-R. Why? Because they look like a turbo pram and have chocolate gear boxes? No, just simply because i can remember them being used in rally and my uncle had one when they were new. There was nothing else like it at the time and i just loved its quirky looks and the fact that Nissan threw everything at it apart from the kitchen sink. Whenever there is a Pulsar for sale on ebay, it always gets around 50 people watching. Loyal fans who want to get their chance of picking up their dream machine.
