Thank you for the welcome,
My gut feeling was for the GS models due to more legroom in the rear, more power ect.., thanks noby76 never knew about the knock sensor, something to check, cambelt I would expect to be high on my check list for been done, are the GS models chain driven?, expect its the tensioners that are the weak link there, I always give the pins a grease up every 6 months or so usually so that does not worry me too much, o2 sensors are easy to fit (or at least on other cars). only thing on the GS450h that worries me is the electric battery on high mileage, probably will cost more than the car to replace.
I have around 4 weeks to find something before the Saab goes for its mot, only other thing that concerns me is winter driving, all my cars previous are fwd, this recent flurry, the Saab did admirably on summer tyres without much bother, I fully expect to have a spare set of alloys and winter tyres for the Lexus been rwd you hear all kinds of horror stories about rwd, probably all running on slicks or something 😄
Right I shall hit the classifieds, and if anyone has a 2005+ GS model up for sale that matches what I am looking for shoot me a message.
Thanks all, I will be logging in most days to browse the forums ect...
