Hiya, can't understand why it's taken you so long to find the very best car in the world to own and drive !!! :winky:
Seriously, I've been driving the LS400 for 8 years now ( this my 2nd. is a 1994 and now at 34k miles ). Just about faultless motoring, safety and comfort and yours at 57k miles not even run in.
Spares can be expensive but if you're lucky you'll never need to replace anything ......... I don't jest ... .. well, maybe brakes and tyres, battery and an oil change, but not much else for a very, very long time.
The cambelt might go to 100k too, but it might need changing at 10 year intervals tho' and that can be espensive but there will be a non- Lexus guy who could do it not tooooooo expensively for you I'm sure.
Just sit back, relax and thoroughly enjoy Rolls Royce motoring at a fraction of the cost.
Pay what you feel is right for the car, there's little depreciation left to worry about at this level and price !
Happy motoring.
