I'd definitely want to try the Regents in the 3rd row before buying, though. That back row has extremely limited leg room, and I could see it being an issue with installing a Regent with the newly mandatory recline bar. Additionally, accessing the 3rd row can be tough if you have seats installed in both outboard 2nd row positions. When we had 3 seats installed in the center row, the "easiest" way to get into the 3rd row was through the back hatch, which wasn't exactly a breeze. If the Regent does work in the 3rd row, I think it would be easier to put 3 across in the 2nd row and only one Regent in the 3rd. Then, you could leave part of the 3rd row folded down, making it significantly easier for that child to get in and out through the back.
The Honda Odyssey has 3 TAs (center LATCH) in the 3rd row for '06-'07.
The '04-'07 Toyota Sienna has 2 LATCH w/ TAs in the 3rd row (one center, one on passenger side).
The Suzuki XL7 '02-'07 has outboard TAs in the (optional) 3rd row.
The Subaru B9 Tribeca
7-passenger model has 2 TAs in the 3rd row.
The '03-07 Mercury Mountaineer has two outboard TAs in the 3rd row.
The Mercedes R-class and GL SUVs have two outboard LATCH with TAs in the 3rd row.
The '05-'07 Mazda5 has two TAs in the 3rd row (see reviews on this forum for information about the 3rd row seatbelt issue in this vehicle).
The '07 Kia Rondo might. The LATCH manual is unclear.
GMC '06-'07 Yukon, two TAs center and driver's side.
Ford '03-'07 Explorer 4-Door, two TAs outboard (cargo tie-downs).
Acura '02-'07 MDX two TAs.
You said "new" vehicles, so I only looked at '07 models.
