I just picked up a new RX450h SEi last Friday and paid £2550 under list price which included Rubber mats / Rubber Boot liner and Back Bumper Rubber Protector plus Supaguard so suggest you try another dealer.
Have just run to Birmingham and back averaging 39mpg which bearing in mind nothing has loosened up yet I thought was pretty good although time will tell
