2007 Ford Five Hundred. They are relatively rare, but completely average looking in every way, totally unassuming appearance. They come in an AWD 200HP option, so I'd use that one. If we are allowed to mod/prep our cars, I wouldn't add HP or anything that would make the engine louder, because ideally you don't want to be noticed at all, and you don't want to get into an active pursuit. My prep would be to make the car very very dirty, put cling wrap over the headlights to make them look really old and faded, get magnet sheets to create the illusion of body damage, along with a magnet sheet over the roof printed with an image to hide the sunroof and make it look like the paint was all faded and peeling. I'd put Toyota badges over top of the Ford ones, stolen plates from an older Toyota Camry, and easy-to-peel-off tint on all the windows. Basically, I'd be attempting to camoflauge the car as an older, crappy-condition Toyota Camry. The plan would be to get to a self serve car wash (casing it ahead of time so I could block any cameras as soon as we got there, probably by spraying soapy water on them) right after the bank robbery, rinse it clean, change the plates, & remove all the magnetic obfuscations. Ideally, the Toyota Camry that we stole the plates from would be at the car wash, and I'd put the plates back on that. The Camry would be in as bad a shape and as dirty as the Ford was camoflauged to be. I'd make sure the decoy Camry was clean of any of my prints, but was full of prints from random people all over the place. Someone uses a ketchup packet at McDonald's and throws it away, collect it and leave it in the Camry. Someone throws away a Starbucks cup, into the Camry. Find a pube in a public restroom, put on gloves, and drop it in the Camry. I'd want so much decoy DNA and fingerprints it looks like 30 people were in the car eating fast food and having an orgy. Maybe have the Camry up on blocks, partially stripped somewhere so it looks like we were trying to strip the car but got interrupted. This would make law enforcement think we were panicking and hopefully alter their search radius focus. I'd be in slacks and a t-shirt, hat, shades, fake facial hair, get out to take care of the outside of the car while the guys stayed inside to lower the back seats into the trunk area, stash the loot and change into suits. The tint would hide the fact that there were people in the car. After The car was rinsed and brand new shiny looking, I'd ditch my disguise after getting in the car, put on my suit shirt, tie and jacket, and as we drove off everyone would peel away the tint. I'd pop the sunroof and drive totally sane and normal to the safe house, which would be a hotel room near a convention center where 4 guys in suits would blend right in. Maybe it's the Minneapolis Institution of Cheese Enthusiasts, a bunch of people from out of town, no one knows each other, etc. We would stay for the duration of the convention, laying low, and then leave when the convention was over and everyone else was leaving as well. We would each have our share of cash in a hidden-compartment briefcase and leave separately from the convention.
