The CR Good Bet symbol is given to models that have consistently done well in our tests and have had consistently above-average reliability.

Major redesign
Here we note the model year or years that the vehicle received significant design changes. In between major redesigns, a model typically remains the same from year to year, sometimes with minor changes in styling, trim, features, or the powertrain.

Drive wheels
This tells you whether a vehicle uses front-wheel drive, rear-wheel drive, four-wheel drive (4WD), or all-wheel drive (AWD). 4WD is available as part-time, permanent, or selectable systems. In both permanent and selectable systems, 4WD can be engaged all the time. Part-time 4WD can't be used on dry pavement. AWD is similar to full-time 4WD, except it doesn't include low-range gearing, which is most important for serious off-road driving.

Related models
To cover marketing niches without having to invest in manufacturing, many car manufacturers sell essentially the same car under different nameplates. Or they may sell another manufacturer's car under their own name. We note any such relationships.

Overview
Consumer Reports' assessment based on testing and research through the years covered.

Safety equipment
We note the availability of air bags (front, side, and head-protection) and antilock brakes for each vehicle. We also note the presence of front safety belt pretensioners. Government regulations require all new cars and light trucks to have dual air bags and to comply with a side-impact standard.

Reliability history
These charts are based on nearly 1.3 million responses to our 2007 Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below.

The scores in the charts are based on the percentage of respondents who reported problems in each of the 17 trouble spots. Because high-mileage cars tend to encounter more problems than low-mileage cars, problem rates are standardized to minimize differences due to mileage. The 2007 models were generally less than six months old at the time of the survey, with an average of about 3,000 miles.


HOW TO READ THE CHARTS

To check on the reliability history of a particular year's model, start with the Used Car Verdict. This score shows whether the model had more or fewer problems overall than the average model of that year, calculated from the total number of problems reported by subscribers in all trouble spots. Because problems with the engine, cooling system, transmission, and drive system can be serious and expensive to repair, our calculations give extra weight to problems in those areas.

To see how the model that's currently on sale is likely to hold up, look at the New Car Prediction at the bottom of each chart. For this rating, we averaged a model's Used Car Verdict for the latest three years, provided the vehicle did not change significantly in that time and hasn't been redesigned for 2008. We have found that several model years' data are a better predictor than the single most recent model year. One or two years' data may be used if the model was redesigned in 2007 or 2006, or if there were insufficient data for more years. Sometimes we include a prediction for a model that is new or has been redesigned, provided its reliability history or the manufacturer's track record has been consistently above average.

To see a model's individual strengths and weaknesses, look at the individual scores for each of the 17 Trouble Spots. The "Average Problem Rates" chart shows the average problem rates for all models in the survey in each trouble spot. Scores are based on the percentage of survey respondents who reported problems for that trouble spot, compared with the average model of that year.

Models that score a  are not necessarily unreliable, but have a higher rate of problems than the average model. Similarly, models that score  are not necessarily problem-free, but had relatively few problems compared with other models.

Because problem rates in some trouble spots are very low, we do not assign a  or a  unless the model's problem rate exceeds 3 percent. If a problem rate is below 2 or 1 percent it will be assigned a  or a  respectively. In the charts, a model year in red identifies the year of a major redesign.

Crash-test results
Where available, crash-test results are listed for the eight model-years covered. We include frontal- and side-crash results from the National Highway Traffic Safety Administration (NHTSA) and offset-frontal crash results from the Insurance Institute for Highway Safety (IIHS). The IIHS uses a four-point scale: Good, Acceptable, Marginal, and Poor.
