They've changed the names/sponsors over the years, and Lagache used to be Nissan or Toyota, and its next to the ACO stand, one of two new grandstands built about 15 years ago to fill the gap between ACO and Jaguar (now Tavano whatever that is). And I think there was a gap - just a raised viewing area - must have been good, as you'll now see all the pits and the track from Maison Blanche to Dunlop from this stand.
I'd recommend a stand seat - somewhere to park your bum at 3 in the morning - and out of the sun and rain - not a lot of room for empty bottles though.
