Keep in mind that this car is at a disadvantage in its class because of
the way ProRally classes are set up.  There's basically 3 two-wheel-drive
classes:
 * Production: small displacement, no engine mods allowed, no turbos.
 * Group 2: small displacement, lots of mods allowed, but no turbos.
 * Group 5: large displacement, lots of mods allowed, including turbos.

That's oversimplified, but the important part is that a 2.5 16-valve
engine can't squeeze into Production or Group 2, so it's automatically
running in G5 with the cars that have huge engines, or turbos or
superchargers.  Driver skill makes a big difference though :)
