I am blown away! Not only did @aquadorhj reach out to me right away when I PM'd me, but he went out to the seller's house the same evening. And if that isn't enough, he read the codes on the car, took it out for a drive and also found the time to write a very comprehensive report about the car. Thank you so much! This is a great community and it keeps giving even after all these years. @aquadorhj, I owe you several of your favourite libations!
Overall, it looks like there's some what I like to call benign neglect going on with this car. At only 49K, it's hardly been driven, but the lady who owns it let a couple of things go wrong without fixing them: Head unit is U/S and shows just the boot screen, for example. Eventually and after 5 minutes it revives itself. Tires (both summers and winters) are shot, chips on the windshield x 2. 2 engine codes which sound like knock sensors according to the interwebs. Anyway, she's going to take it to the dealership for a diagnosis and it will give me time to think about whether to make an offer on it. I know these cars well and nothing so far in @aquadorhj 's report makes me worry but I'm not going to go all the way out to Calgary to drive the car back to Ottawa without getting it at a fire sale price.
Thanks again!
