By this time in a classic cars life, when most of their brothers & sisters have found their way to the dismantlers & the remainder have slipped comfortably into the hands of the enthusiast, most of the hardy perennial problems have been attended
to.
The problems, when they come along are fixable with updated/ rated replacements, created either by the manufacturer (usually in a panic) or by the string of pearls, in the form of people like Mike Satur, Darren at ‘Bitz, Jon at Rough Luck, et al.
It must be a great disappointment to turn up a lemon amongst all the sweeter fruit that are around, especially when it is from a reputable dealer. I can also understand the resistance from your better half who probably didn’t want in the first place.
I can’t second guess how you will extricate yourself from this situation, all I can say is that if/when you get clears of the smog & are into clear air you’ll love the experience of driving one of the last truly British sport cars & at a price that can still be afforded.
