Road worthiness of car after flooding damage

Hello, I drove car through a flooded bridge, car stalled, water trickled into back footwells only. Car towed to garage. Diagnosis two bent con rods. Head taken to be skimmed and con rods replaced and vehicle now ready for collection. The incident happened 23 Dec, 4 hours away from where I live, and vehicle sat in open lot for best part of ten days (no dryers used) before garages re-opened so I have no idea if car smells, or will need to replace carpeting. This is my only car and I have read the worrying reports about trouble with mechanics and electrics in the months ahead with flood damaged cars. I just would like an honest opinion as to whether I should offload the vehicle as soon as possible or whether safe to continue using it for a couple of years ahead. I will also be driving it back the four hour stretch along motorways and am very concerned about the safety of it. Garage assures me all fine but would just appreciate a second unbiased opinion. Many thanks.
