I have an 11 month old 2005 MY05 WRX
WRC Blue 6000 kms imac, exhaust, tint, bonnet & light protectors, moulded mudflaps, carpet mats, $2k stereo, 12 months rego and I would consider myself lucky to get $35K private sale.
So remember, your car is only worth as much as similar vehicles being sold.
My 2 cents worth.
