Anyone give a rough idea of what the repair cost may be for slamming into wall on freeway curve

It is hard to provide a precise repair estimate without inspecting the vehicle and understanding the extent of the damages. However, here is a general idea:

A minor incident with no significant damage to the structural components (e.g., just some scratches and minor dents) may cost between $500-$2000 to fix.

A moderate accident involving damage to the vehicle's body panels, bumpers, or suspension components could cost anywhere between $2,000 and $5,000.

A severe accident involving significant structural damage or damage to vital systems like the engine could easily exceed $10,000 in repairs.

The actual cost will depend on factors like the type of vehicle, the severity of the damages, and the hourly rates of the auto body shop performing the repairs.

Getting estimates from multiple reputable body shops will give you a better idea of the repair cost and help you decide how to proceed. Remember to factor in insurance deductibles and potential coverage for any accidents.
