2013 Subaru BRZ

If you've tried to weasel your way into a Subaru BRZ for a test drive lately, you likely know just how hard it is to get your hands on one of the machines. The rear-wheel-drive coupes are flying off of dealer lots as quickly as they arrive, but according to USA Today, a spot of sibling rivalry has pushed Subaru to offer a small incentive on the BRZ already. Customers are already ponying up an average of $29,085 for each BRZ model sold. Compare that to the $25,653 average transaction price for the virtually-identical Scion FR-S, and you can see why Subaru offered a $400 incentive on the BRZ in June.

The FR-S, meanwhile, moved with no cash on the hood.

The two companies have very different approaches to selling the cars, however. Scion offers the FR-S in one standard trim in either manual or automatic guise, while Subaru offers two trims. The more expensive of those includes niceties like leather seating, automatic climate control and a proximity key, but compare base model to base model and the Subaru is $1,315 more than its Scion twin.

According to USA Today, Scion sold 2,684 FR-S models across 1,000 dealers in the U.S. last month. By comparison, Subaru sold 818 BRZ units over the company's 600 dealers.
