I have a Lexus LS430 at the moment, which is just over three years old, and only completed 26,700 miles, I am contemplating changing it for the LS460, Last week a hired a Golf Plus with a diesel engine in Germany and I was most impressed by the engine’s torque and fuel economy, so I am wondering whether I would be better off buying a MB 350 CDI car, even though I have never had a diesel car in my many years of motoring. Would I be better buying the LS460, the MB 350 CDI, or keeping my present car for a few more years as my wife would prefer? As you will see I only do a very low mileage in the year, although I do like two or three continental trips per year. I would appreciate your knowledge and wisdom on the subject.
