Why do we label the Sileighties as such? They are just Nissan 180 SXs (or even 240 SXs in some cases) that are modified with the Silvia front clip and not official models... I would suggest we list them as Nissan 180 SX with Sileighty Conversion in extra info, if at all. With the current reasoning we would have to list every Acura Integra that some ricerboy mounted a JDM front end on as a Honda

Indeed.
We could include the "Sileighty" name between quotes in extra info, like what we do for common nicknames. It would be less "heavy" than mentioning "Sileighty Conversion".

Done all except this one because I don't know enough about the cars to distinguish them the others were easy as they were all in the US, so 240SX, save for one 180SX in F&F3
