Have you recently been in an accident? Is your car salvageable and needs repair? There are European Car Care that specialize in taking care of cars after a bad collision and can restore your car back to as original shape as it can get.
Professional European Car Care that take care of collision will often offer a towing service to where you can tow your car directly to their shop and have them start working on it right away. It is important you specify the type of car you have so they can be certified to take care of you personally for your make and model. If a shop can’t, they probably will have connections to another shop or another mechanic that can help you.
If you are looking to have body work done, that is going to be different than engine work. All the parts will have to be sent away for unless they have them in stock which will usually take a larger shop to have a warehouse of parts of many different cars. But it is possible that you can get in and out in one day depending on the severity of the damage and their schedules.
