Narrative:

While my friend was receiving weather information inbound to ZZZ; I saw an aircraft directly to our left at the exact same altitude (2;400MSL) headed to our right. My friend was writing and listening to the weather from the front seat and I was in the back seat. I immediately grabbed controls and turned the aircraft left; while we both watched a twin engine plane fly across what was now our right side. My friend immediately made a radio call after safely transferring back controls to my friend in the front seat and there was a responses of 'ZZZ traffic; I think I just saw you; I'm over the lake'. We landed in ZZZ and after about 15 minutes a twin aircraft that appeared to be what we saw in the air landed and parked in a hangar in ZZZ. The near miss was very close and at the exact same altitude. Had I not been a passenger in the back with a view of things closer to the aircraft (as opposed to my friend's view of things further from the aircraft) this story may have ended differently. Also; our aircraft had the right of way and the faster twin was not spotted against the horizon while scanning for traffic prior to the incident.
