Can't recommend this as it's been broken for years without a fix. The cabview is broken, so that the windows do not display the outside, which I believe is quite an easy fix, espcially for the devs.. And it requires the EU Classis Asset Pack to display in game AT ALL, since it just installs to where the normal HST are, and then adds the buffers as child objects. But if you don't have the asset pack it has nothing to apply these child objects to, soooo it doesn't work.
If you do already have that pack, it's a bit more considerable, since you will get a fair few more skins for the HST, including non-buffered Virgin examples, but I think these still suffer from the cab view bug.
If you can stomach having a worthless cab view, and you already have the EU Asset pack, it's good for having at this price especially on sale. But not really. Idk.
