I've got a 940 turbo as my daily driver and i haul a lot of computers around with me. The real issue here is it's a sedan and at most i can fit 4 computers in the trunk (already gutted the speakers and cd player for more height) and 3 computers in the rear passenger seat.

i was thinking of cutting through the rear body of the car to make the rear passenger area and trunk the same, building a flat padded board to make around 10ft x 4ft of wagon-like space. I will post pics in a bit for reference...

My questions are:

• Will this make me in any way fail safety inspection? (there are cars with fold down rear seats all over, but thats from factory).
• If I did this, should i reinforce the body with a beefed up swaybar or weld in a bar just below the rear windshield to compensate for structural loss

The solution to my issue is not "go buy a wagon" so please don't bother posting that. This 940 is mine, it's here to stay.

 

well say you cut that piece out and something happens like structural dmg or an accident. Your insurance co. most likely wont pay for any repairs when they inspect the vehicle. Something to think about

 

I'll plea the "don't bother posting that" option.

 

cutting anything out of the way the car was designed will effect the original structure since everything was designed to work together.
that being said i myself have turned trucks cars and even a minivan in to a full time topless vehicle(sorry no pics of any but the unfinished minivan, was before the days of more than 28k internet).
i ran into something similar with my last toy a 1997 plymouth breeze(dodge stratus) though mine was more challenging. i was wanting to turn mine into a prototype made only station wagon but of course there was no roof that was a direct fit for this application.
long story short if you have access to a welder go to a junkyard and find a simular year wagon thats about to be crushed with the rear doors back area in good shape and cut off as much as you are able to get there(you can always trim down to what you need later)take note of the differences in the over all bracing while you are cutting so you can add bracing where needed. really depending on the junkyard and if you cut it yourself you can get all of it for less than the wood would cost to build it and the finished product would look better and be more secure for your computer equipment
