Thanks for the warm welcome guys.
Just took the car into Lexus Hull for a "once over" as it still has three weeks manufacturers warranty left.
Thought i might as well see if anything needs doing.
Looks as though previous owner looked after it well.
Only thing they did was upgrade the EPU settings to the latest revision.
The only other thing that i picked up, which is annoying more than anything else, is a strange "squealing" noise from the dashboard area when putting the vehicle into reverse.
The guy at Lexus said that he noticed it and that if i booked it in next week when they had a little more time they would sort it out. Seem to be very helpful - nothing too much trouble.
Hopefully this will turn out to be nothing major - anyone else suffer with the "mouse noise" when reversing ????
