They should do. I've just put seats from a hatch into my estate.
The backs need fettling as they don't fit right, but apparently if you switch the foams over from the metal backs they fit perfectly.
Cant say about vento seats though - if they're the same as the hatch, theyll go in with fettling. If they're the same as the estate due to the same floorpan they'll go straight in.
