Performance - enough power for normal city driving, but feels underpowered when driving uphill. My house is on a hillside and I have to drive uphill every time, but personal driving is OK because my car doesn't have to pick someone up. I don't use it as a family car because my family can only buy one or two cars each. So they can drive their own cars and not have to ride mine. The car is sufficient for personal use. Interior design - the tachometer and odometer look nice. There is an LCD screen that shows fuel consumption, tank information, mileage, odometer numbers, etc. The player is still fine, but the screen size is a little smaller. Unfortunately, there is no Android, no access to the Google Play store, and no access to standalone players. It needs to be plugged into the phone to mirror the screen, but I generally don't like to use the phone cable in the car. The sound quality of the speakers is very good, the sound quality of the Bluetooth is very good. Still, there is some disappointment. The screen surface of the air conditioning panel has been scratched too much since the first day I got my new car. I don't dare to polish it because I'm afraid I'll mess it up again. The compartment is too small even to fit in a Toyota service manual holster. The center compartment is small, but I only use it for microfiber towels. Security - I will not comment on this for my own safety. It is a 360-degree panoramic bird's eye view, suitable for careful parking. There are also seven airbags that make me feel safe to drive. Finally, it has a front and rear line dashcam, which makes me feel more secure because the CAM is recording the evidence. Design - The design has been good so far. Most people say they don't like the front bumper grille body kit. That's acceptable to me. I don't think it's ugly. Different people have different thoughts and ideas. The only thing I don't like is the color of the paint. Toyota does not offer a gray for the VIOS. Sadly, I only got silver metal. I don't like white, blue, red and black. Blue and red are shiny, but I don't like them. Black looks too dull, so I don't like this color. Therefore, the only best color left is silver metal. It's sad that Toyota didn't offer gray like the Vios 2014 did. Grey metal looks smoother and more lustrous because it has a darker color on the painting surface, while silver metal looks too old and although it has luster, it is not as smooth as blue and red. In addition, I am working on making metallic silver into a mirror-like glossy surface. I now try to wax the car up to 10 layers if possible. Toyota didn't offer gray for the 2019 version of the VIOS, which is a bit disappointing.
