Remember if you base it on doing over 25000 km a year and end up only doing 24000 then that can end you up with a big tax bill.

On the numbers you have provided the STi is about 12 grand more over the 2 years after the residual. Probably be close to that in resale difference at the end so cost you more while leasing & closing out lease but end result will not be much.

I did go the STi on a lease and I wouldn't change it for a WRX no matter how much you twisted my arm.

Think you might find the WRX a little "soft" coming from a fairly hardcore car.

Tyres befitting an STi will cost you more than 800 a set.
