Welcome Digga, good to have you with us.
As Daniel has said-all good points for your consideration.
I would suggest ALL SEASON TYRES rather than WINTER tyres. Michelin cross climates are superb.
Daniels`s comment re length of car is very important and Lexus is not like a BMW or Audi as progress is linear not accelerative. Reliability is a given.
My only additional comment is do read and digest the Handbook as it is more important than owners realise.
Do enjoy both the Forum and the ES.
Send piccies in due course !👍👍👍
