"Green" is a word that has come to represent much more than a color over the last few years. We're constantly bombarded with ads talking about how "green" the latest hybrid economy car is, and how it might just save the planet. Despite the growing popularity of this new definition of the word, Mike Pennington decided to build a car that returns to the roots of what a green car can be—and it's certainly not a sluggish 4-cylinder hybrid.

This week's featured customer car story is a little different. We received the following letter from Steve Martinson, of Idaho Falls, Idaho. The Martinson family (Robert, Steve, and Darcie) owns the stunning blue 1968 C10 restoration project seen here, and Steve described the build so perfectly, we decided to share his words verbatim. Enjoy!

R/T--two letters that will instantly put a smile on the face of any classic Mopar enthusiast. Representing "Road/Track", the R/T package bridged the gap between an ordinary street car and a hardcore track machine. In the case of the 1970 Charger seen here, the R/T badges mean it came standard with a 440ci Magnum V8 that produced 375hp and a whopping 480lb-ft of torque. The R/T model also included heavy-duty suspension components, simulated scoops on the doors, sleek one-piece tail lamp trim, and a longitudinal rear "bumblebee" stripe. In 1970, the Charger R/T replaced the Charger 500 at the top of the model's three-level performance hierarchy (aside from the race-ready Daytona model).

The term "bubble top" has become a catch phrase in the Impala restoration community, and we often hear people asking what it really means. Take one look at the rounded roof of this 1961 Impala coupe, and you'll start to understand. The curved glass, smooth lines, and lack of B-pillars cause this car's roof to appear similar to a bubble, hence the name. The term became especially important one year later in '62, because GM produced a select few Impalas with leftover '61 "bubble" tops before transitioning to the more angular "crinkle top" later that year.

In today's world of extremes, subtlety is an often underrated trait. When it comes to automotive restoration, there's certainly nothing wrong with building a vehicle that turns heads everywhere it goes, but sometimes it's nice to fly under the radar. Tony Pellegrino, the owner of this 1972 GMC truck, wanted to build a pickup that featured tasteful modifications without going over-the-top. So, he chose a 3/4-ton C2500 long bed model with subdued white paint, and added a few parts to make it his own.

If you're a car enthusiast, especially a classic car enthusiast, you'll no doubt know that air suspension can be a controversial modification. Some people love the ability to tuck big wheels and adjust ride height on the fly, while others claim air suspension degrades what would otherwise be a nicely restored classic. No matter your stance, it's hard not to appreciate a car with air suspension that looks this good. Eric Sass, the owner of this '62 Chevy Impala convertible, embraced the controversy by purchasing the car in mostly restored condition, then swapping the stock wheels and suspension for a set of 'bags and deep-dish billet wheels.

If you imagine a muscle car, odds are that you picture something with wide tires, a loud exhaust, a huge motor, and aggressive styling cues. Although this traditional interpretation is undoubtedly cool, there are many ways that the idea of a muscle car can be interpreted. Here at Classic Industries, we love muscle cars of all shapes and sizes, and that's why Jack Petitt's refined take on a muscle car is so appealing to us. Jack restored this deep blue '69 Nova with the help of his daughter, and together they created a car that's as sophisticated as it is powerful.

Here in southern California, the mention of a 1962 Impala makes many of us think of one thing: lowriders. Impalas, especially the '62 and '63 models, are extremely popular among the lowrider crowd, to the point that we see quite a few of these cars roaming the streets of SoCal while riding low on wire wheels and whitewall tires. Case in point: this '63 Impala SS that showed up in our parking lot not long ago. However, there's much more to this era of Impala than the common lowrider style. This '62 Super Sport coupe was built as a lightly modified cruiser, and features a timeless design that anyone can appreciate.

Throughout history, prized possessions have been passed down from generation to generation. If you were lucky, maybe you inherited a massive tract of land or herd of livestock from your father—if you were unlucky, maybe you got a bottle cap collection. Although we don't typically depend on our inheritances to define our futures anymore, important items are still passed from father to son (or daughter) as family heirlooms to preserve. The 1965 Chevy C20 seen here is one example of a family heirloom, and through son Gary Skinner's loving hands, his father's old truck has been reborn.

As much as we love time-tested, untouched classics, there's also something to be said for building a car that's truly original. After all, that's the spirit of hot-rodding—putting together something unique with little more than spare parts and ingenuity. It may not be popular with everyone, but it'll certainly turn some heads and raise some eyebrows. Rebelling against the status quo might yield a total failure, or it might yield something that changes the world—you never know until you try.
