Welcome to the LOC :) , i've had my IS200 SE about 15 months,i bought it from an independent garage, saved about £1300 of the main dealer price, it had full Lexus history, so i contacted the dealer to confirm the service history, then once that was done i had a HPI history check done, this all checked out ok so i bought the car :D .
My alloys had been refurbished before i bought the car, they had been done in silver all over, so no machined/polished rim to worry about, just a silver paint stick to touch up....if needed.
My interior is the beige "oakham" trim, this can look shabby if not looked after, a set of Lexus over mats helps, but they to can get dirty very quickly...other than that i have no complants B)
