Yes and no. If you simply resize something to make it bigger the file size will increase but it won't make it 'high res'. In terms of this sort of thing, it will be made bigger yes but also re made at that highe resolution to give a better quality.
That is understandable, someone else once said the same thing. It's actually my rl car (and baby) a s2 rx7. I think the XR is more similar to the later series rx7's (4 and 5) personally but it is hard to tell with my small avatar pic.
