Hi Frankie (me luv yoo looooong time
Some of these things have been mentioned before but,
Look for the rear 3 legged spoiler.
The front splitter may not be there as they break easily.
The interior should be half "leather", actually vinyl
There are no check lights on the panel above the ashtray except for the "door open" light.
The side skirts should be coloured, although the bumpers may still be black.
They only came in red or black, so any other colour would be a bit strange.
There should be a sticker badge on the rhs of the bootlid saying "Silverstone", although these can probably still be bought somewhere.
The Silverstone is actually a very base 1.8litre 8v so only front leccy windows and maybe a sunroof.
Also check the drivers head rest moves properly. You can tilt it up and forward so your head rests on it while driving. Great for track days with a helmet as you can tilt it right back so you don't crick yer neck.
