Roof spoiler for '98 Accent Coupe

Hi all,

I'm looking to purchase a roof spoiler (nice and tastefull small-one,
not a surfboard!) for my '98 Accent Coupe.

It doesn't look like an official spoiler is available although I have
seen such spoilers for sale on the net, for instance at
www.performancefx.co.uk/HYUNDAI.htm although their prices are putting
me off a bit.

Have also tried looking in salvage yards with no joy.

Just wondering if anyone has fitted a roof spoiler to their car,
possibly may know where to buy a decent one for reasonable money
(preferably from within the UK) or if spoilers from other makes/models
of car are also suitable for my car.

Also, are there any problems in fitting a spoiler around the rear
wash-jet?

Thanks.
