It's like any enthusiasts car... sometimes people want to move on from their car and with mods a car is worth nothing to a dealer. There are a bunch of Subaru enthusiasts going from tricked 2.5RS's to the WRX, and selling their 99, 00, and 01 RS for between $14k and $18k with suspension & exhaust upgrades, sometimes w/turbo. The reason to do it is because a 2.5 turbo is faster than a 2.0 turbo, even when the 2.5 runs 5lb of boost peak and the 2.0 runs 15lbs peak. It's something to do if aftermarket is your thing... and if aftermarket is your thing then you won't really care about reliability. To clarify, in my post about picking the RS I meant stock, not with a turbo. IMO it's the best combo of cost, speed, handling, and versatility for this guy.
