Forg I'll be interested to hear how you get on at Alto Holden.
Oops, somehow I didn't see a whole bunch of other poasts, it looked like Skylarking was responding to me when I said the above.
I've had Alto do stuff in the past (wagon rear wiring harness recall), they were fine then, didn't wash the car when I asked them not to. Same last week when I had the horn fixed (loose connector at steering-wheel - caused when Hunter replaced the wheel due to leather trim delamination) and the tailgate switch seal reinstalled. They did that stuff in one day, Hunter needed me to come back because they didn't have the parts (seems odd Alto would have more parts just lying around - surely if you want to get parts, as a dealer, you can do exactly what indy mechanics in the main cities do & just get 'em delivered same-day?).
I also didn't have to reassemble the tailgate striker trim nor the steering wheel trim, unlike Hunter. They do appear to have gotten a little bit of grease on the driver's door titanium Alcantara trim (it's very slight, probably only lightly brushed it with a hand or elbow), fortunately they haven't tried to clean it off & make it worse (which reminds me - need to see if Car Care Products have anything to clean it
carefully).
To be honest, I was really quite impressed with Camden Valley Holden. The cost of the rental for the day wasn't much at all (I think $45 for a base Cruze which isn't highway robbery for a 1-day rental IMHO - my guess is it'd be a Chinese-built Astra sedan at the moment) and it's perfect weather for a Southern Highlands day-trip.
But it does mean taking a day off, which isn't optimal.
Back to Alto … be aware that Lane Cove West is a fork of a place to get in & out of by public transport, and the shuttle they provide has to go along peak-hour Epping Road so takes an interminable amount of time. They had service under the (now Benz) dealership up at Chatswood last time for me, which was easier to get in & out of. Next time I'm going to pre-book the Macquarie Park Keoride, if heading towards Chatswood or the CBD it's probably worth checking the 285 bus schedule (bus stops right outside their front door) as at least it gets bus lanes (and is pretty empty there so you'll get a seat).
