Don't know if I'm being way too picky in my search for an LS400, but this one seems a bit overpriced IMO. Why mention the boot seal and brakes done around 3 years ago? I'd want to know more about the last 3 years, which have been glossed over a bit.
I saw another Mk IV up for sale recently for half the price - It was a bit tatty but had a recent cambelt and loads of work done, to me it's more important that the owner has spent the money on important mechicanical work than tacky V8 badges.
Maybe I'm wrong and being too harsh, but these are expensive cars to fix if something goes wrong, and considering he's not willing to budge on price, it would have been nice to include more detail about the services and any mechnical work, MOT advisorys etc..
