Well they kept my 172 for 3 1/2 days and have replaced my steering wheel with a new one after the insert on the old one split. They have finally replaced the mid section of the exhaust which has cured the 4k rattle, this is the fourth time it has been in for this. Previously they kept going on about it needing new bolts on the heat shield which suprisingly never fixed the problem. It is now waiting for a new actuator motor for the air conditioning which is currently on order.
When I went to pick up the car, I collected the keys and got into it, as soon as I turned on the ignition the stereo was on and really loud, so I switched it straight off, anyway, today I used the stereo for the first time since the car being in and guess what, I think they have blown some of my speakers, they are all working, but the rear ones are now rattling/distorting at low volumes.
Its f*cking useless, I take it it to get one thing fixed, and through there own disregard for someones car trash my speakers.
Chris.
