wrx sti?

[speedfreak]

hi i currently drive a lotus elise but am selling her soon as just need a change of scenery really, had my mind set on a tvr but not sure if i want to spend £££ on maintaining her, just saw top gear mag and like the look of the new wrx sti, and just wondered if it is a good car and if anyone has any info on the car, i would be getting the prodrive 300bhp upgrade.
the price seens really good value at £26990 and sounds easy to maintain, just want to know though if the re sale value is good or do they depreciate alot?
many thanks for all your help
