The Skyline combo makes me think that somebody had a box of leftover bits and made a car out of them.
If this is your first Jap turbo car, I'd probably be looking at one that has only been lightly modded. We all crawl, walk run......
The S14 would be OK, but its heavily modded, if you don't have a big toolbox or intend to circuit race then its outta your league imo.
