Driven by movie stars when new, and cherished by collectors today, the 250 GT California Spider is one of the most valuable cars on the planet
Largely built for the American market, California Spiders were that bit more sporting than the 250 GT Cabriolets they were based on. By 1960, just under 50 long-wheelbase versions were built with 240bhp engines. The wheelbase was then chopped by 8in to create the short wheelbase (SWB) version. Power went up to 280bhp and another 50 of these were sold over the next three years. They can be worth as much as 40 per cent more than the LWB cars, but the rare alloy-bodied versions of either (just 12 built) could easily exceed the £10m mark.
Add 40 per cent for SWB prices.
