Research the market value using online resources, consider factors like mileage, age, condition, and location, and negotiate with the seller based on comparable listings.

• Check the vehicle's handling, acceleration, braking, comfort, visibility, and listen for unusual sounds. Test all features such as air conditioning, audio system, lights, and brakes.

It depends on your budget and preferences. New vehicles generally come with warranties and the latest features but depreciate quickly. Used vehicles offer cost savings but may have higher maintenance needs.

Factors to consider include budget, purpose (commuting, family, recreation), fuel efficiency, safety features, reliability, maintenance costs, insurance rates, and resale value.

Clean the interior and exterior, perform any necessary repairs, gather maintenance records, and consider getting a vehicle history report to show potential buyers.

Be honest about the vehicle's condition, history, any past accidents or damage, maintenance records, and any known issues.

While a collision history may affect the resale value of your vehicle to some extent, properly repaired damage should not significantly decrease its value. Ensure that repairs are completed using high-quality materials and techniques to maintain the vehicle's integrity.
