We have a scraper bot already @Croc
Hints to refine the tool is one discussion
If you're just looking for a good Duratec SV I'd have a budget of around $40k and it goes +/- from there depending how many others want that similar color/spec, location, registration docs etc at the same time.
Full range would likely be about $35k to $45k+, likely going more towards $45k due to 420R spec being closer to top of the range.
