Thank you all so much for your feedback. Your comments are all very useful and I have written them in a notebook so I can ask the right questions when viewing the cars. Seriously I am hopeless when it comes to buying a used car. Now I know at the 6th service, there will be sparkplugs to change and will ask if they have already been done etc. It;s a very good point about the tyres, if the car has different tyres, then I should probably avoid that one as its owner probably don't look after the car much.
I did think about getting one of the Hybrid GS but I had a Prius years ago and its gearbox failed me when it reached 6 years old. That kind of put me off a little bit on the Hybrids now.
I currently lease a Volvo S90 and will have to hand give it back in a few months, so I am starting to look for a car to keep going and I don't fancy leasing again.
If you don't mind me asking a question on the Sat nav, I saw some used GS have a really wide Nat Nav screen. Is that an optional extra? If so, what is the name of the Sat Nav which comes with a wide screen? I presume the standard sat nav on a GS 250 would just have a standard 8-inch type of screen, ie not the really wide one?
Thanks all. Much appreciated.
