A lot of "high-end" products are just fancy marketing
Alcantara is increasingly popular in tons of performance cars. There's good reason for that -- it's nice to the touch and can even help you grip a steering wheel better. Just don't think of Alcantara as some ridiculously special, space-age material, because it's basically Ultrasuede by another name. Your grandmother's couch is perfectly alright in the interior of your car; all I ask is that you're cognizant of what it is.
A square wheel setup is a good thing
No, I'm not talking about attaching angular blocks to your car. Many years ago, almost every single car came from the factory with four identical wheels and tires -- which is called a square setup. Today, though, a lot of cars, especially performance cars, come with rear wheels and tires that are wider than the ones in front. This is called a staggered setup, and while it tends to look great (one of the reasons manufacturers do it), drivers that are serious about performance often switch to a square setup. It affects the handling balance of your car and also allows you to rotate tires, which helps them to last longer, saving you money.
