Chips away arent the best mate. I used to work at Audi, they have their own spray shop in Hillngton. The sales department used to bring in chips away because it was cheap and nasty, so thy didnt have to pay a bit more for a decent job.
Sometimes they even had to come back, due to it being such a bad job because it was air drying, and not forced heat drying. I had my Impreza resprayed at JB Coachworks, it was expensive but the job looked like it had just came from the factory, I wouldnt trust anyone else.
Remember, its YOUR car mate. Why should you have a 2nd rate job because the girl that HIT YOU, decided she didnt want to stump up the cash for a good job. If thats the case, go through the insurance...
When getting quotes for damage, pick 3 companies your HAPPY with doing the job, and then approach the 3rd party with prices. All GOOD jobs should be priced around the same ballpark figure.
