Like everyone has said these are two very different cars. The IS250 is a luxury car and the Z is a sports car. So it really depends on what you're looking for. I've spent a lot of time in my bro's IS250 and so I'll try to give you some perspective on both cars. The interior in the IS is much nicer. The leather is nice and soft, dash layout is elegant, super quite inside, plenty of room in the back, but what I liked the most is how deep the black color is on the gauges/dash and interior. It looks more appealing, where the Z kinda looks like a faded black. I always felt a little disappointed hopping back in the Z after borrowing his car. Since you're not going to get much power out of the IS, tuning the suspension is a must. I remember how dull the car felt stock, but after lowering it and throwing on some bigger wheels and tires, I can honestly say I was impressed with the grip and handling. It felt like it was on rails with little body roll. As far as looks, the Z is the eye catcher when you compare them in stock form. But once you hook up the IS its a sexy looking car. Personally, I always felt more ballin driving the IS, but I always felt like a boss in the Z. The power difference is night and day, the Z is loud, a little rough, and does what you want when you want it. No matter how you look at it, the Z wins in every performance category. The interior design is great, it feels like a racing cockpit designed around the driver. The gauges are all staring you in the face and everything is within perfect reach.

The Z is a more driver focused car, if you like driving as much as I do, then the Z is the one you want.

If you like nice materials when you cruise and you're not worried about performance then the IS is the car you want.
