Guys you can do what I do... to hold off the "insane family name calling" lol.. (for your next car that is...:edit lol)
I bought my car before I told my parents I've bought it.. they "knew" i wanted one... in that mean time I got around to dropping the rear, putting on Charcoal Grey TwiNTurboR 5spokes and removing the tint and putting in the pod filter.
...... then...
I rocked up at home one day "Look mah... I bought my car!" lol not that way but trying to put some humor into it... and yeah... so as far as they are concerned that's how "I" got the car... obviously later on when I do big HP work... they'll be cool by then.. since i'm apparently holding off so long atm. LOL
