I'm going to disagree, slightly. 
This is a hefty model, 25mm x 14mm, as large as many MBTS in my collection, so I'll call it a Class 3.
The weaponry consists of a pedastal-mounted MG (separate piece, glues next to the hatch) and a two-barreled turret on the front bumper (with a terrible arc of fire).
Here's a simpler version (no ECM, no PDS, not amphibious, chemical-fuelled, basic targeting, carrying two regular infantry teams):
Equipment Item VSP : BVP Spaces Cost
Vehicle, class 3 15 : 0 15 15
Armor class 3 15 : 24 15 24
Chemical Fuelled Engine 15 : 24 15 29
Hi-mobility wheeled 15 : 24 15 36
1 class 2 RFAC
in Full traverse turret 15 : 24 9 46
with Basic fire control 15 : 24 9 50
1 APSW 15 : 24 9 50
Space for 2 units of
normal infantry 15 : 24 1 50
I counted the turret as the free APSW, and the MG as a class 2 autocannon.
Or, drop one infantry team, raise the turret to being two Class 1 HELs (which is as large as you can have without upgrading the power supply):
Equipment Item VSP : BVP Spaces Cost
Vehicle, class 3 15 : 0 15 15
Armor class 3 15 : 24 15 24
Chemical Fuelled Engine 15 : 24 15 29
Hi-mobility wheeled 15 : 24 15 36
2 class 1 HEL's in Fixed mount 15 : 24 11 60
with Basic fire control 15 : 24 11 62
1 APSW 15 : 24 11 62
Space for 1 unit of
normal infantry 15 : 24 7 62
paints another Grey Knights squad.
