I think it's a great idea
In Italy there are not many Esprit,. This is because the taxes are getting higher and many sports cars have been sold abroad.
We thought the price of Esprit, still in Italy, would go down again. But it seems that every owner has agreed and now it is impossible to find a good Esprit under 30000-35000 €,if you want a daily runner with some work to do then you will spend about 22000-25000€
50000€ for a good V8 and 45000€ for beatifull S4s.
I have to say that we are a little luckier in Italy. There are not many rusty cars here , often you can find not restored Esprit, like mine, that if you look under her she looks like new and absolutely without rust:D
I think the Excel in England is a bit underpriced, in the rest of Europe the prices are higher.
Unfortunately in Italy there are no Excel, I just think my own and another one and maybe only 4 or 5 Elite eclat

I think the price for a good Excel can be between 20000€ - 25000€ and if restored in show conditions about 30000 €,
