OK, I purchased this car a few months ago when it had already done 249,000k's. I looked at many VR Commodores before I bought this one. Some with only 130,000k's and some with 170,000k's etc. I ended up choosing my one with 249,000k's for a couple of reasons that I will point out.
It is a one owner and has been serviced every 8 -10,000k's from the same dealer it was purchased at - Regular servicing is most important. These cars run so smooth that some people feel that they can skip services, but it will show with age. The car has not been in any accidents, and the auto has been reco'd around 200,000k's. The auto is the only problem the previous elderly owners had ever had on the car and they attended to it straight away as they weren't short of cash. The car has always been kept undercover all it's life and the paint is beautiful, there's no crap in all the small little nooks and crannies such as leaves etc... And last, but not least the lady owner was sad to see it go so I knew it had been loved.
Above all this I did get it thoroughly checked by my mechanic for peace of mind and it came out with flying colours.
My main point that brought me to write this is that you shouldn't necessarily be turned off by a car that has done more k's. ALL of the cars I drove before buying this had as low as 130'000k's and none of them came close to feeling as nice as my 255,000k calais to drive. Make sure you get a service history with your car and you're not buying it from some young idiot who's thrashed it coz its going to have problems. A one owner purchase from a more experienced driver who you know hasn't thrashed the car is definately a bonus.
My car is really nice and smooth, has plenty of power and is suprisingly economical if you don't give it too much stick.
