what i find funny is that so many people are comparing a car that sells for over 20k-25k after 15 years with a car that cost that brand new.
try taking into account the cost of buying the car, doing it up and how fast it goes then. i know a guy that had a dirty old exa that ran low 13's and the car cost him about 10k all up. that was on stock internals, stock ecu.
another of my mates had a GH sigma that had a stock sr20 in it with just a front mount, exhaust and more boost that ran a 12.56 at the 2005 jamboree. the car cost him $5000 to buy the car, motor and do the conversion.
wrx's are a completely different car to the GTR. they are aimed at 2 different markets. the GTR was aimed at the supercar type of racing, so it has taller gears, etc and makes a better track car. the WRX is more rally based, so its not such a good track car.
i know if i had the option of either a 25k, 100% stock gtr or a 10k, 100% stock silvia and then spending the other 15k on making it go fast i know which way i'd go. sure the gtr would get a better launch, but once you get moving the silvia would soon flex its muscles.
but you guys keep having fun comparing your cars that cost well over 50k new to cars that cost 20k and cost about half as much to run.
