Thanks.
So generally assume it's not been done then unless invoices/evidence. Thing is with so many owners hard to understand what exactly could have been done without the evidence, even if it may have been.
Also, from your comment, get services done at Lexus to maintain full Lexus SH and then additional preventative work at specialists?
Yeah getting an an enthusiast ISF owner to come along and check the car and pay them for their services would be great. Otherwise, thanks for the main dealer info - getting them to look over it to get to 10/10 will really help. I'm just wondering how to incentivise the owner to do this though before buying...
