The S was available in full or half leather options. On the half leather, the rest of the interior was finished in matching "ambla". How can I tell which interior is in my car ? I could prod it and see if it goes "moo"
The seats do look a different texture to the rest of the interior. The doors, transmission tunnel, and dash all have a uniform texture, so are synthetic.
I have never heard of "Ambla" before. Is it just a posh name for Vinyl dreamt up by TVR ?
