White or silver V6 Toyota Camry. Your average person wouldnt be able to identify it from a Nissan, Subaru or most family sedans butbits still got enough guts for a little spirited driving to let you put distance on quickly, turn a lot of corners and make establishing your ultimate direction difficult.
You arent trying to outrun or out drive the cops, you need to get a few dozen blocks away in a car nondescript enough that its hard to track or set up a cordon in time, dump the car and switch into something else (Ideally multiple other vehicles) equally nondescript
I posted this and forgot to comment. There are a many cars less than 10 years old I cannot identify without badging but I would go for a mid sized SUV. They tend to blend in everywhere. Pick a model with a fast engine, upgrage the wheels/tires a little for better traction, etc.
The Ford Flex AWD would work but may cost more than the actual bank heist haul.
