If you live on a bumpy road, you want a car with a smooth ride.
If you live on a bumpy road, you'll want a car that rides smoothly. Even if you don't live on a bumpy road, it's hard to go anywhere without encountering at least one bump. Even the brand new roads in Florida have bumps, it's like they put them in there on purpose so the road crews will have something to do later besides standing around watching one guy dig a hole with a small shovel . . . but I digress.
The perfect Mopar for bumpy roads kind of depends on the size of the bumps. If the road is really bumpy, a big truck would be nice. If it's just kind of bumpy, a big C-body like a Chrysler Imperial would probably ride the best.
If you don't ever drive on bumpy roads then any kind of car would ride pretty smooth, so you don't need to waste your time reading this blog.
