Good day all, i purchased a 2000 LX 470 with 38k about 4 weeks ago. posted on here and a couple days later decided to buy Lexus Platinum Warranty (which goes 3 more years or 100k total miles)... it cost about $2600...
well, the day after i bought it, i had a long road trip for biz... heard most annoying rattle from the rear seat... took it back to dealer, they had three guys go out in it to look (driver, and one guy each laying on floors to listen) they heard it immediately.
turns out is was a defective seat track, not only annoying in rattle but maybe even safety hazard... well, Lexus ordered new one, installed, provided warranty, whole nine yards, NO QUESTIONS ASKED.
i own 2 lexus, i guess that makes me a LEXI owner... 96 es 300 (91K) and 00 lx 470...
go with dealer warranty, more expensive, sure but well... go with the best and they will treat you great!
good luck.
