If your main reason for exchanging your car are the new safety features, I'd like to put a grain of salt in the discussion. In Germany the different Yaris trim lines have different names, but I suppose that they basically are the same cars. I have a 2016 Yaris Hybrid Style Comfort. I bought it second hand, so I am not entirely sure which accessories were basic, part of the Style Comfort package or paid extras. I put my assumptions in brackets. My car is equipped with a lane assist feature (basic), an automatic high beam assistant (basic or Style comfort), safety sense anti collision system (Style), a multimedia car stereo with rear view camera and handsfree phone (Style), Alcantara seats, both front seats with heating and height adjustment (Style), keyless entry, cruise control, foldable arm rest at the drivers seat and power windows on all doors (all Style). The car has a black top and a spoiler at the rear window, it also has privacy glass (tinted rear windows), which may be some design package. It came with 195 tires on 16 inch rims, which probably also belongs to Style. My car lacks only two accessories which definitely were accessories, the satnav system and the additional plate to put into the trunk to get an extra compartment (don't know the English word). It may be that the Style Comfort line in Germany is exactly what you call Excel in UK. The later 2018 models got a different radio with Google Car Play, a different steering wheel with some sort of joystick button and a new cockpit with an app which detects speed limit signs and shows them in the cockpit. I am a gadget kid, so I love things like the keyless entry and the cruise control. I enjoy the rear view camera which makes parking really easy. My car has a middle rear mirror which adapts to the brightness, this works flawlessly. Actually, my main reason to buy such an expensive car (other cars with lower trim levels would cost less) was the front passenger seat with height adjustment. I am a very tall person, so I need every inch I can get. As for the safety features: I am not so convinced with them. Lane assist works flawlessly, but all it does is beep three times when you cross a line on the road with indicators off. Well, a decent life seems imagineable without that thing, in most cases I switch it off. The high beam assist first worked remarkably well, but some days ago it worked that bad in the dark that I had to deactivate it. The problem: If the assistant is on and thinks it is not dark enough for high beam, you cannot override it. The most complex safety assitant probably is this presense thing, which detects objects you may collide with. It has a design flaw: It relies on a camera located in a box behind the middle rear mirror. This box is glued to the windscreen, so the camera sits in a small chamber and looks through the screen. When it is cold and wet, this chamber can get foggy, and then the assistant won't work. This would not be such a big problem, because before I bought this car I survived without such an assitant. But when the camera can't see, the assistant switches off, and a bright, orange warning sign begins to blink in the speedometer. You cannot turn this sign off, there also is no way to get into the tiny chamber to dry the windscreen with a piece of cloth. You can switch off the presense assitant, then the blinking stops - the warning sign stays lit. And if you switch off the engine and start again, the assistant is activated again. I cannot tell about the traffic sign assistant, but I think it is even more useless. In brief: I bought my car with all the bells and whistles, because I needed the height adjustable passenger seat and I really wanted the cruise control. My wife loves the backview camera. However, If I would already own a Yaris Hybrid which runs flawlessly and I would not need the extra space, I would seriously consider not to upgrade to a new car. If you want cruise control, you can have it installed for approx. 250 GBP, you basically need the control lever and somebody who can activate the software. I do not want to question your plan to buy a new car, and a little car, fully loaded with very nice gadgets has a charm on its own. But I would not spend much money on the additional safety features. If safety is a major concern for you, spending some money on a safety driving training may be a better option. Best regards from Bavaria Frank
