Did You Know - Subaru WRX STi Edition

Everything You Need to Know Before Buying a Subaru Impreza WRX STI

So you want a peanut eye or hawk eye WRX STI? Our buyer's guide will give you an idea of what to look out for.​​​

What to look for

The later 2005 model looks much the same as the '04 (Subaru enthusiasts call these years "peanut-eye"), but comes with the 5x114.3 bolt pattern that would extend over the next decade, that all-important immobilizer, and a revised interior. It's a little heavier than the '04, but otherwise identical.

For 2006, Subaru switched up grille to something resembling an upside-down Alfa-Romeo, and moved the torque split further forward to 41/59 front to rear. The 2006s also have unique aluminum front control arms, offering bragging rights more than an actual performance enhancement. Specific issues only really apply to the easily-replaced liquid-filled motor mounts. Some Subaru fans consider the '06 to be the best year for both the STI and the WRX.

What to avoid: 

A bad first impression isn't the end of the world. Subaru paint was apparently applied by the good people at Crayola, and is highly susceptible to chipping, fading, and scratches. The body panels pick up a dent from just looking at them too long, so spots and ripples aren't necessarily accident damage, just Subaru cellulite. Something to watch for is the paint on the Brembo brakes; if discolored by heat, it's likely the car's been on the track.

The STI is also a very noisy car to drive. All Subarus more than three years old develop rattles–it can sound like there's a mariachi band fighting a rattlesnake in the dashboard. Add in a loud transmission and little sound deadening material and you might go a little deaf.

However, there are things to listen for on any test drive. First, almost all STIs can suffer from the rear struts clunking over bumps. This issue can be resolved with disassembly and lubrication, but it's a pain. Of greater worry is any actual grinding coming from the transmission. A little clutch judder is normal, and the gearbox can be notchy, especially when cold.

You should, of course, have any car you're considering for purchase inspected by a reputable mechanic. In particular, you may want to have a compression and leakdown test done as the STI is very susceptible to knocking (either from bad fuel or a poor tune).
