Hi, some Hyundai chassis codes to add:

All Trajet and Trajet XG have chassis code [FO]
All 1986-91 Grandeur are [L], all 1992-97 are [LX]
All 1998-2004 Grandeur and Grandeur XG are [XG]

Technically, [XG] should be applied also to US/CDN XG 300/350 and EU XG/XG 30, but maybe would be a bit redundant? None of these has the code currently from a quick look and anyway searching for XG would include those ones
