I thought I'd start a thread so that I can ask silly questions and hopefully get some advice etc.

Here's a picture I took at the dealers, the only one I've taken so far but I'm sure that will change!

I'll have a bit of a better look over the car in the next few days but some minor things I want to sort are,
My car has the 'Sport' pact apparently, so come with harness bar and Schroth harnesses. It currently has the drivers harness fitted and seat belt removed and just the regular seat belt on the passenger side. I think it 'looks' better with the harnesses but obviously is slightly more convenient to have the option of a seat belt.
First question, can I have both fitted at the same time each side? (Car came with both the passenger harness and removed seat belt)
Next, it was a bit damp and foggy on the way home and I noticed the windscreen wiper is a bit naff, can't remember from my S1 days if this is just normal but I'll probably get a new wiper anyway so it there an upgrade? Aero blade style etc. or simply a new one from somewhere like Eliseparts?
I've also noticed the headlining is a bit saggy, this will probably bug me, I've replaced a few headlinings on old Saab Turbos so I'm guessing it's gust a case of unbolting the roof and either re-gluing the headlining or sourcing some new material and gluing that on? I was also considering getting a 'long scoop' roof instead.
Two other cosmetic jobs I'd like to sort are tidying up the engine bay, removing rusty looking bolts etc. Are there stainless steel fixings available? And the decals have been removed, already ordered new 'Queens award' and rear 'Exige', not sure I'll even re-fit them yet

Thanks in advance for any help!
