Thinking of downsizing to a motorcycle at the moment. What do you think the polo is worth on the market now?

2006 Black Polo 45000km
Seat intake
forge front strut
whiteline RSB
Koni sport kit (adjustable shocks +spring)
lower honey comb grill
alpine type x speakers + alpine x001 ipod unit + rockford fosgate p450.4 amp
2 year extended warranty left.

i suppose most will not add much value to the car, but rather, have some value as an individual items.

what you guys think?
