996GT2 long term keeper

[catsey]

Appreciate thoughts and opinions . I have a 28k 996GT2 ex Rob Huff so a bit of providence with the car which is debatable. the Car is unmarked 2004 comfort but mod to Club spec with upgrades (tubi exhaust etc engine tuned to 600bhp)
I drive the car when im home in Summer but contemplating putting it on the market or keeping it. .
Will this car ever reach the dizzie heights of collectable value that other GT2,s are realizing.
I drive the car in Summer when im home in UK so to a degree its not a garage queen.
