Agree, absolutely. Whatever positive effect he may create for the USA will be at a cost charged to the rest of the world

Whilst I am unable to furnish a wiring diagram for any element of an RX400..... Would I seem unreasonable to enquire whether the OP's enquiry is somewhat terse, overly abbreviated and not just a little obtuse and inconsiderate? Manners?

Brilliant! Rabbers. I think it's wonderful to witness someone whom enjoys their food, and knows how to broaden their experiences too. I 'doff me titfer' to you, Rabbers.

I afraid, that I'm happy to say a couple of belting Islay Malts serve my palate well. Laphroaig Quarter Cask, or Lagavulin 16 year old. Either 10% room temperature water, or neat. And a favourite wines are a ten year old Barolo, or, maybe Montrachet or a decent Chablis. The real issue is that I have a champagne taste, and a beer pocket! But what little I have, I enjoy.

It's great to see a solid dose of common sense!

That's a first-class update, Barney, and thank you for the details.

After 4 years of driving our 2014 F-Sport, it's currently on 33.6 mpg (combined winter/summer, 95% about town, 5% motorway)

The Lexus dealership I use replaces the batteries in both keys on every service. And as these batteries only cost pence, then one can always replace them oneself every six months (if one wishes) just for peace of mind. Think of it as 'preventive maintenance!'

I think you'll find that the clue is, Robert lives in Perthshire!

I look forward to reading of your results - - I've oft wondered how effective it can be

Hi Jag, I had a Catloc fitted (by our Lexus dealership), (for there had been a few cat.s disappear in our locale too), and so far, so good. However, you're right that there is not a guaranteed method of protecting one's cat, although I believe the two important cat.s on your car are beneath the bonnet, and the unit underneath the car is less critical - (that's the unit protected by the Catloc)

Andrew, whilst I'm not in the market for tyres, I think you would help a response if you gave more information: Size of tyres Make / model of tyres Age/wear?

My experience is that whilst I only get about a 5% improvement in mpg using premium fuel, (or, now, E10 with a fuel additive), I feel more comfortable hoping that the claimed additive ingredients counter some of the possible adverse effects of E10. And I've convinced myself that the engine is smoother, - (it isn't of course, but I'd like to think so!) Most importantly, - my mpg has improved over the few years I've had the RX, not because of magic, but I've learned how to drive it more efficiently in different road/traffic conditions. It helps that I'm never in a scalding rush to get anywhere!

Rob, the 3rd Generation RX450's don't suffer from canbus thefts.
