Would gravity decrease time by accelerating car toward sun?
If the Sun was a point gravitational source an object at 1 AU with zero angular velocity would take (1/2)(5/2) years ~ 64 days to drop to the Sun based upon a Keplerian ellipse with semi major axis of (1/2) AU. So think about 2 months.
It takes an object at 1 AU with zero angular velocity

{ (1/2)(5/2) - 1/[3π (2 x 2003)(1/2)] } years

~ 64.55 days to drop to the Sun's surface.
