easy question about adding a spoiler
 

How does the spoiler attach?
remember I don't have an SVX handy to look at.

Can I add one, change my mind and remove it without much trouble or work?

The spoiler has 4 studs that go through the trunk lid and are attached by 4 nuts (obvious) underneath. Some people have added spoilers to their "un-spoiled" SVX's. Apparantly the locations to drill the holes is somewhat obvious when you actually take a look at the underside of the trunk lid.

I think...
 

If you check under the trunk hood, there are indentations which are guide marks for drilling/attaching the spoiler. If indeed holes are made in the trunk lid then removing the spoiler would require a patch repair on the finish...
