This is a really good point and I hadn't noticed. I wondered why my garage, with its Lamborghini and Ferraris didn't have my beloved Impreza. I remember always checking the Subaru dealer every time I was looking for a specific car, wondering which of the Impreza's I'd buy, balancing cost vs tunability vs model (I prefer the slightly older ones, its a shame my '03 isn't a premium).
But I never bought one, and now I realise why. I don't have a Lancer either. Of course I'll eventually buy both as part of my collection, but thats not the point.
There is a trophy for a Lancer Vs Impreza race but there isn't actually such a race, so do you have to create one? How do you even do that - practice mode and fingers crossed?
