Introduction

Aim

I had some difficulties doing this the time restriction, missing data because we only used 100 cars we could have got more from the autotrader exchange mart. I could have taken it further by comparing the models and makes, looking at other factors such as the engine size, condition, type and the model of the car. I think these other factors together with the things like mileage age and make all together contribute to the price of the car.
