Looks fantastic!
Are there ducts in the front panel? Mine does not have these. No wings on cowl? I dont have them either!
I also bought a series 1 garage queen about 18 months ago - mine on 6k miles.
Also had air con issue. Mine had a new control module and a wiring mod which is apparently a quite common issue - there is a factory fix for this which believe it or not disables the recirculation function!,
See you still have what look like original Pirellis. My car had been stored under cover all its life but the compound on the tyres had gone hard and handling was lethal - would seriously consider changing them if they are original.
Hope you enjoy it as much as I enjoy mine.
