Year Of Car
The year your car was made. If you're not sure, open your door. On the inner doorframe, there's a decal that should have the year it was made.
Automatic: You have no clutch, all you do is shift into drive and stomp on the gas.
Manual: You have 3 pedals (gas, brake, and clutch), plus a shifter. If you have manual and don't know it, I worry about you.
Semi-Automatic: Called a number of different things, such as "Sportmatic" "Manumatic", all sorts of nonsense. Only found on new cars, mostly luxury ones. It lets you clutchlessly shift your transmission. NOTE: Cars that have "low" or just "1" and "2" are NOT semi-automatic.
Number of Doors
... the number of doors your car has. If you have a hatchback, count the hatch as a door (so a 2-door hatchback would put 3 doors).
The number of ponies your engine is worth. If you're not sure, look up your car on cars.com. If you have added "performance" modifications, do NOT put your "estimated" horsepower, because we all know that intake of yours doesn't add 20 horsepower. Put only dyno tested horsepower, or your stock horsepower.
The pulling power of your engine, in ft/lbs. If you're not sure, look up your car on cars.com. As with horsepower, ONLY give dyno-tested or stock torque.
The curb weight of your car, in lbs. If you're not sure, look up your car on cars.com. It will be in the specifications.
How your engine "breathes". Most normal cars are Naturally Aspirated, but newer model diesel engines and some sporty cars are turbocharged or supercharged. Ram-air refers to a system in which air is forced into your engine by the speed of the air. Its most often done with a hood scoop, although some hood scoops are merely decoration (namely the Mustang). If you're not sure, look up your car on cars.com, it will be under the performance section. Look at the engine "type", if it doesn't say "turbo gas" or "supercharged", your car is naturally aspirated.
Look on the side of your tire. You should see a series of letters and numbers that reads something like this:"P185/60R14". The number after the R is your wheel size, it'll be something usually inbetween 13 and 19.
The first part, the stereo type, is self explanitory. The wattage of your stereo isn't always very well known. It may be in your owner's manual, but most of the time its not listed at all. If you have the stereo that came with your car and its not a "premium" stereo, it'll probably be somewhere inbetween 40 and 100 watts. "Premium" stereos are generally 100-180 watts. If you have had a stereo added after your car was purchased, say from Best Buy, then your wattage will be listed on the front of the reciever. Give your total peak wattage, so if it says (40x4), you have a 160 watt stereo. If you have added an amplifier, include that as well.
Look in the back of your car at the pipes sticking out the back.. these are your exhaust pipes.
Single: You have one pipe coming towards the back. You will only have one muffler. Your pipe may have a chrome or dual exhaust tip.
Double: You'll have two pipes coming out, and two mufflers. This is NOT to be confused with a dual-exhaust tip, which will have two exhaust outlets in the back, but only one muffler!
Quadruple or more: You don't have this. If you have four pipes sticking out the back, most likely you have a dual exhaust tip coming from two pipes. Very rarely I have seen these on extremely large vehicles, but I don't think you drive a semi.
Oversized: Select this if you have any type of exhaust, whether its dual or single, with an extremely large exhaust tip or muffler. You guys know who you are that have this.
Most cars have Halogen headlights. If you drive a new luxury car, you may have HID headlights, check your owner's manual. HID headlights are brighter and look purer. Xenon/HID lookalike are bulbs that you can put in your halogen system to make your car LOOK like it has HID headlights. However, these are nowhere near the real HID brightness or spectrum. If you think you installed your own HID system, you didn't. Real HID systems cost $2000-$3000, require completely replacing your wiring and everything, and are illegal in all 50 states. Tinted/hyperwhite are merely halogen headlights tinted a little blue.
Global Positioning system, found on many new luxury cars or rental cars.
Speed Sensitive Steering
Adjusts the sensitivity of your steering wheel depending on what speed you're going. Found on many luxury cars, as well as all Saturn S-series sedans and coupes.
A window at the top of your car. If you have a moonroof or T-top, check this also.
If your wheel is all one piece, you have alloy wheels. These are most often found on sporty cars, although recently many cars are coming standard with these. If you have hubcaps or "wheel covers", you do not have alloy wheels.
