Car Price Dataset

This dataset is a synthetically generated collection of car specifications designed to simulate real-world automobile market data. It contains detailed…

The market share distribution across the six brands in the dataset has been visualized in an interactive donut-style pie chart. The chart clearly shows each brand's proportion of the total vehicle count, making it easy to compare their relative market presence.

The highest-priced combination of brand, fuel type, and transmission is Ford + Petrol + Automatic, with an average price of $49,822.74 across 34 vehicles. A horizontal bar chart shows the top 20 combinations ranked by average price, making it easy to compare which configurations command the highest values in the market.

The bar chart visualizes how average resale prices change as the number of previous owners increases. You can clearly see the price trend across different owner counts — generally, cars with more previous owners tend to have lower resale values.

Honda leads all brands with the highest average car price at $46,584.09. Two visualizations were generated to help you compare brands: a bar chart showing average prices per brand with color-coded values, and a box plot revealing the full price distribution and spread for each brand. These charts make it easy to spot not just which brand is most expensive on average, but also how consistent or variable pricing is within each brand.

Petrol vehicles command the highest average prices at $47,132, while Electric vehicles are the most affordable at $45,711 on average. However, the price differences across all four fuel types are surprisingly small — only $1,421 separates the most and least expensive categories. Two bar charts and a box plot were generated showing the price distribution across fuel types.

Two charts and supporting data tables were generated to help budget-conscious buyers identify the best price-per-horsepower deals across brands. The bar chart ranks every brand by their average cost per horsepower (lower is better), while the scatter plot compares average price vs. average horsepower with bubble size indicating how many models each brand offers. Together, these visuals make it easy to spot which brands deliver the most power for your dollar.

Across all brands, automatic transmission vehicles are priced almost identically to manual transmission vehicles. The overall price premium for automatic is just $194.79 more on average — a negligible 0.4% difference. Two charts and data tables have been generated to show the breakdown by brand.

The analysis reveals how vehicle prices vary across model years from 2005 to 2023. Interestingly, newer model years command higher prices, with 2023 models averaging $52,719 compared to $39,917 for 2005 models. The total price spread across all years is about 24.3%, which works out to roughly 1.3% per year. Two charts were generated: a line chart showing average and median price trends by model year, and a bar chart showing value retention percentage relative to the peak year.

There is a strong positive correlation (0.614) between engine size and price — meaning larger engines generally come with higher price tags. The analysis also identified 4.8L as the optimal engine size for value, offering the lowest price-per-liter ratio at approximately $11,057 per liter of displacement. Two visualizations were generated: a scatter plot showing the engine size vs. price relationship colored by fuel type with a trend line, and a dual-axis bar chart comparing average price and the value metric (price per liter) across all engine sizes.

A bar chart has been generated comparing 2-door versus 4-door pricing across brands. The visualization uses a red-to-green color scale to clearly show which brands charge a premium for 2-door models (green bars above zero) and which offer a discount (red bars below zero), with a dashed line marking the break-even point.

The analysis produced a bar chart showing the price premium of single-owner vehicles over multi-owner vehicles for each brand. The chart uses a color scale (red to green) to highlight which brands command the highest and lowest premiums for single-owner history.

Two interactive charts were generated showing how fuel types have evolved across model years from 2005 to 2023. The first chart is a stacked area chart showing the percentage share of each fuel type per model year, while the second is a stacked bar chart showing the raw count of vehicles by fuel type per year. Together, these visualizations reveal how the mix of fuel types has changed over nearly two decades.

Low-mileage cars (under 30,000 miles) command a price premium of $3,181 — that's about 7.0% more than high-mileage vehicles. On average, low-mileage cars sell for $48,924 compared to $45,743 for higher-mileage ones. A bar chart shows how average prices decline across mileage ranges, and a brand-level breakdown reveals how this premium varies by manufacturer.

The analysis identified the top 20 brand and model year combinations with the highest prices relative to their age. Two interactive charts and supporting data tables were generated to visualize the results. The horizontal bar chart shows the top 20 combinations ranked by average price per year of age, while the scatter plot reveals how price-per-year varies across different car ages and brands.

Across all fuel types, larger engines consistently correlate with higher prices, but the strength of this relationship varies. Two scatter plots and trend lines were generated showing how engine size and price relate for each fuel type, along with an average price line chart across engine size ranges. Petrol cars show the strongest engine-price relationship (r=0.654), while Diesel shows the weakest (r=0.573). The overall correlation across all fuel types is 0.614 — a moderate positive relationship.

The analysis produced a bar chart and box plot comparing average horsepower across brands, along with data tables breaking down each brand's HP statistics. The bar chart highlights which brands fall above or below the overall fleet average, with above-average brands shown in red and below-average in blue. The box plot reveals the spread and distribution of horsepower within each brand, making it easy to spot which brands consistently deliver high-performance vehicles. Brands sitting well above the overall average horsepower line are the clearest candidates for targeting the performance segment.
