I drive a 2007 VW Jetta TDI and have a 10 month old son who is tall and slim (30" and 20 lbs.). We currently use a Graco SafeSeat but he's going to outgrow it soon. I'm looking for a convertible seat that will allow him to sit RF as long as possible and have narrowed it down (I think!) to the First Years TrueFit C670 the Britax Blvd and the Recaro Signo G2. Also considered the Graco MyRide. My priorities are maximum RF, good SIP and his comfort. I'm concerned about RF comfort for my little guy and also the size and fit in my small car. Any thoughts? We spend A LOT of time on the road. Our second vehicle is a Dodge Ram extended cab 4-door truck so the Jetta is the main challenge. Any advice will be much appreciated!
