Hi Diesmile,
They bought brand new Mode 2014 in Syd, the IS350F is blue in red, I personally think it is the best combination. I'm in Brisbane and the best dealer could do here for IS350F+EP1 is $76000 (three years service for corporate programme,duties cheaper in QLD). if your budget is around 60K, I would still recommond you the demo IS350Fs,10k kms is nothing for a Lexus. the 3.5L engine is a GEM, it beats the BMW 335! it is in totally different world from the 250 or 300H. once you drive the 350, you will know. in addition, 3.5L engine doesn't have the carbon build up issue like the 2.5L and fuel comsumption on my car is 9.7L (70% highway) Also,the steering with VGRS(only in 350F and SL model) is sharper. Now Lexus has MY2015 out, with some upgrades in lights, and also reverse alarm which could detect side incoming vehicles, make sure you take this into account when negociating with dealers, might worth wait a month or two.
If you are not a "fast"driver, another good choise might be the BMW 320i, with 17 inches tyres, it is comfort and quiet (surprisingly quieter than the IS), and you get all the fansy technologies, such as HUD, electronic tailgate, 360 view camera etc.... someone I know bought MY14 New 320i sports line, sunroof, 5 year/80 K service pack, in Mel City BMW, driveaway was $54500 and in Brisbane the best I got was $61000 for a 320i with luxury line, sunroof, metallic paint, innovation pack(must have,all the good technology stuffs) and the 5 year service pack. tried the 320 Msport and 328i but the ride is to rough for me. However for 320i, the ride is actually quite comfort (not as good as Lexus though) and the powertrain, chaissis and steering are all top of its class.
Good luck and let us know how you goes, cheers!
