Every vehicle has two costs: a one-time blueprint that unlocks it at a track level, then a spawn price each time you bring it out.
Helicopters: MH-6 Little Bird $6,250 [BETA] to spawn, Pilot 0, no blueprint. AH-6M minigun Little Bird $7,000 [BETA], Pilot 4, $50,000 [S1] blueprint. Z20 Lakota transport $7,400 [BETA], Pilot 10, $35,000 [S1] blueprint. Havoc $18,000 [BETA], Pilot 35, $500,000 [BETA] blueprint.

The Season 1 changelog confirms the AH-6M, Z20 Lakota, URAL and SPH-2 blueprint prices and the Driver and Career levels. Spawn prices and the other blueprints are wiki values it did not change, which is why this answer is Likely rather than Confirmed.
The M113 APC is free. It appears at your base when any faction reaches 20 points and works as a team spawn point once parked.
