1993 Cadillac Seville STS Reviews

when I brake pedal and the car is hard not to
overheating issues
I love the way my car drives, smooth and comfortable and everything inside works. Only problem is the pretty fake wood trim around the gear shifter is breaking away. If I keep my speed below 65 I get between 25-35 mpg with cruise on, of course, depends on the road grade too. It is costly to maintain the way it needs.
