Actually the placement of the steering wheel is not much of an issue. All you need to do is convert your headlights for lhd-traffic. Additionally here, i needed to add a rear foglight and those fugly reflectors. (Don't worry they'll be gone soon^^)
But to get started, belgium is rather strict on carmods... that means you need to find a car that's as much as possible in stock form, just for the homologation on belgian roads. If you get lucky you can get through with a lowered car... but no guarantee.
But i'm really stoked to be able to finally drive it. It took almost 6 months from start to finish.
