Brian I totally agree with you, I was just saying that between the two alternatives (buy two gt4 and switch interior vs make new interior) maybe the latter is less expensive.
However, if I am not wrong, the sunroof was made specifically for the US market, that's why it's plenty over there and why in Europe it is almost impossible (maybe a car with us specs) to find one.
Original sunroof cars are mostly US and UK models.
Finding an euro model could take decades. I've seen some
really nice UK models but RHD feels pretty funny,
although it's better for the track.
As far as switching interiors - seats come out readily,
carpet is the same color so it can stay, the most difficult part would
be the door panels. Guess I'm talking myself in this direction.
You'd end up with two cars in non-original interior colors,
but I think I've seen less than 1% of sales having the certificate of originality from Ferrari Classiche, so it's not a biggie.
If I'd bribe anyone would be the guy that bought mine,
but so far he's not as foolish as I was
