Wow - that doesn't sound good. I've had great service from Solitaire in the main. I've bought 2 Golfs and 2 Lambos from them and found them very competitive every time. Or are you talking aftersales service?
Sales was fine - was the attitude of the service dept - 1st time was in 1999 - had just purchased a Audi A4 2.6 V6 - drove it back from the Riverland 3 times as the car would literally die when pulling out onto the Sturt Highway (with a limit of 110km/h) and having a truck literally eat your rear view mirror whilst the car would limp to a halt! - after 3 times to be told that I was imagining it, last straw car blocked the local hospital entrance for 3 hours and I bypassed them going direct to Audi Australia who had the car towed back to them. After a week - same service manager rings me saying that I had to take the car back as there was nothing wrong with it and it was taking up space in their yard!! I refused and told him to keep looking - poetic justice - he drove the car home that night, going across the Cross Rd/Princess Hwy intersection - it died on him - towed it back and it was a faulty radiator sensor causing engine management system to shut down to prevent overheating!
A few episodes in between then 2nd significant time was with the Q7 - only 2 months old - spare key would not disarm/arm/start car - took it back and service dept said tell your wife to take it out of her handbag so things would not press and accidentally drain battery!!! (SWMBO was NOT IMPRESSED!!) - a week later, same issue, key was sitting on bench entire time!! Appears car was so new they could not "reprogram" it locally yet at the time! (We sold the Q7 after 4 months!!)
A few other minor service dept incidents along the way too and recently with my a VW I had bought my dad to use!
My gripe is every car can have idiosyncrasies/incidents but treating customers like idiots was definitely a no no in my opinion!
