Hi Justin,
You must have given up expecting a response from your post!
The LS430 is the best car in the world!
I had one in the UK for four years and 85,000 miles without a problem
Now living in NZ and missed it so much I bought another and imported it from UK. Mainly because the LS430 on sale here don't have the sat nav screen. That's important because it controls the audio and air con through touch screen
Yes the mark levinson system is totally awesome. I have bought and fitted an iPod/iPhone connector which you can control from the screen and the resultant sound quality is outstanding!
You must get the updated LS 430, it has 6 gears and a better looking front end.
The wheels are the only vulnerable item, subject to corrosion, but a refurbish sorts it out.
The car is so quiet some people think its a hybrid when it pulls away!
I get 12.5l100km on average and on a steady run will get 9.8l100km.
My car is very cherished, stays in the garage if raining, the underside has been shot blasted, galvanised and epoxy painted!! The inside is like new, everything works perfectly and has had full Lexus service history with 50,000 miles. Not everyone's choice in colour, it's gold, and I had the wheels refurbished in body colour. I think it looks amazing.
My friends think its a new car, I tell them it's 8 years old and they don't believe it!
The Rolls is a great idea, but the Lex will be a better drive, with amazing performance too.
