Chopard Mille Miglia - some pointers please

[Grey Ghost]

I have a large birthday later this year and would like another nice watch to mark the occasion. The Chopard Mille Miglia has caught my eye but I don't know much about them other than I like the look and feel of them and they appear to come in a variety of model numbers and finishes.

I am happy to buy pre-owned and have seen several so far that fit my criteria; stainless steel case (possibly titanium), rubber strap (may consider leather), white/silver face and Arabic/baton markings. There appears to be a significant range in prices from c£2300 upwards to something that would require a mortgage and I have even seen one with a tyre gauge as part of the boxed set

Can one of you more learned folks give me a few pointers as to what might be a good buy and where to look, max budget will be £5000. Also, I have seen some nice ones on Chrono24 with dealers in NY, Miami and Frankfurt that have good feedback posted. Is this a good place to buy and are the dealers known as prices here appear to be lower than UK dealers and I would gladly buy online (NY and Miami dealers) if they were recognised and offered a watch with the full set of papers and box.
