Well I've just bought one !
From Lexus in Tunbridge Wells, four years old RX 300 SE Navigator, Glenmuir Blue and Oakham leather with all the bits plus parking sensors, sunroof, boot liner and new wool mats for £14995. One elderly owner and 15,000 miles, had its 40,000 mile service a month ago, looks like it has just come out of the box, immaculate unmarked condition.
Thank goodness for depreciation.
Sales staff were excellent, polite and helpful, got the trade in I wanted for my mothers old Focus, a great experience all round.
