It may seem peculiar, but the value of your car can vary throughout the year due to seasonal fluctuations in prices.
For instance, selling a convertible in spring can be advantageous as the weather improves, and there's a heightened demand for such vehicles. On the flip side, entering autumn and winter, interest in 4x4s and SUVs tends to rise as these models are better suited to winter weather conditions, leading to an increase in prices.
