Let me just say this; I had a choice between the LS460 2009-20 or the LS430 2006. I went with thte LS430! A more quieter engine, very reliable, transmission issues are unheard of! I testdrove the new Jag a still i went with the LS430.
You just need to drive both cars the same way. Research the dealer that will be servicing your baby and do a side by side comparison; then make your selection. We are LS430 owners and a little bias. But we have been driving these machines for some time now and now our Lexus'.
After six months of driving your LS430, you will discover something new that you did not know this car could do.
