So you're starting to get a little older and have added a couple members to your household. As a parent, most car trips seem to involve carting the kids to school or sports practice. However, you occasionally still find yourself testing the grip of your tires on the expressway on-ramp, followed by full-throttle acceleration to match -- or maybe even eclipse -- traffic speeds. It's time to shop for a new car that will accommodate your family, but under no circumstances are you willing to buy an SUV or minivan. You longingly remember the days when a blue-blooded sports car was parked in your driveway, but there's no way you'll be able to regularly drive one of those again (at least until the kids leave the house). But your life as an automotive enthusiast isn't over ... it's just time to consider an exciting four-door.
