It does and on the whole, so long as they aren't completely abused or neglected, for the age and performance you are gonna be pretty right.
I think the thing is, the Skyline is a mainstream type car in this country, which attracts a greater audience or potential buyer who may not completely understand performance cars in the first instance - hence the additional fear - which is not necessarily founded on much.
For instance, magazines, Hot 4s and the like, talked about the GTR's additional maintenance required. But for the performance, it is not that much, compared to say a Porsche, or a Ferrari. But a fellow Japanese car, like Civic, it is a lot more expensive to own.
