One Of Everything
That old Hyundai was the cheapest car I've ever driven. The steering wheel must have been bolted directly onto the axle because I felt every bump in the road. At speeds over 60mph the whole car would shake and the steering wheel would rock rapidly back and forth under my hands. Absolutely terrifying and absolutely fun.
Through my life I've had many cars and I've narrowed down what everyone *must* own in their lifetimes. You need a convertible. Mine was a '79 Fiat Spyder but any rag-top will do. You need to experience the sun beating down on your head, the wind blowing back at you from behind the car and the absolute joy of feeling completely exposed whilst driving too fast. The world never will look better to you than it will from a convertible.
You also need a pick-up truck. You become the 'guy with the truck' to all who know you and it's really fun to be called upon to help your friends and family out. A unique experience. Also, you can create a redneck swimming pool by putting a blue tarp in the back and filling it up with water. Don't forget a duckie float with your cooler of beer sitting on it! (Yes I've done this and yes it works wonderfully). Mine was also a 4x4 and I recommend that you also learn to drive off-road. Many fine adventures were had in that truck...maybe they'll make it into another post...
A luxury car would be next. Do I really need to explain how nice it is to ride in comfort? The only problem is that you'll never want to leave that big plush seat. My plush car was a late 80s Oldsmobile. Damn that was a smooth yet powerful car. And large enough to do dirty stuff in the front seat.....
The boys at Top Gear had it right when they said every car-lover *must* own an Alfa some time. I would extend that to *any* Italian car. You'll never have a car that you'll love and hate so much as your slick Italian car.
Lastly you should own a sports car. It's marvelous to go fast, to quote the flick Grand Prix. Mine was an '88 Supra. My friend had a Chrysler Laser and we would do things with those cars that would later make it into Vin Diesel movies.
I would write more but I have the overwhelming urge to go out and look at my rather mundane Honda Civic. That little car is possibly the best hunk of metal and plastic I've ever owned. It takes the miles and the abuse and gives back pure loyalty. I'm going to kiss 'er and leave a lip mark in the dirt on the window.
