Very desirable cars, saw this today.
Off topic, but with you having a SZ, saw an SZ too today.
The owner was gutted, he has had his SZ about 5 years and within the last year the whole body has had a massive outbreak of micro-blisters on every single panel, not small ones either, absolutely covered.
He has had estimates as high as £18K to get the whole car stripped back and painted. Didn't know this was a potential SZ problem, and car is garaged too. Didn't take a photograph as I thought it would be inappropriate.
