This is looking great - I forgot how much I love the 88-spec interior. I had a black 88-spec XR3i (also an E reg) and remember way back then the in thing was to switch to 90-spec interiors, so I picked up a pair of red fleck Recaro's for half the price of the later ones, chucked em straight in to match the rest of the interior. I thought the darker grey was much nicer.
Yours is looking really clean and I love the home restomod.
