That's good news then. Are they starting the job asap?
when my corsa had it's rear quarter repaired it went on for weeks. at first they couldn't get the parts, then they forgot to book the car in at the same time as the courtesy car and so on. in the end, when it was all booked in, they still didn't request the parts on time and a 4 day repair took 10 days in the end. I even turned up unannounced at the repair centre to check on their progress and wasn't happy with the work they'd done so far so they had to re-do it.
don't let them fob you off on anything Doug. always keep track of what they're doing and write down the date of when they committed/agreed to something so they can't backtrack on it.
