There are converters who does mod from LHD to RHD in US/ UK, and AUS, and their quality is at par with the original factory.
I've a friend own a late generation Mustang in HK too, but it's rare to see him driving that car (His was shipped from Australia, where it was sold through dealer and converted by Tickford)
haha, I've driven both Evo. and the pony, and I like the pony better, also, the Chrysler 300M HEMI is great too, but too expensive, it cost almost 700.000 HKD, which in US, u can get 3 of the same car...300M ranges from 21,000USD to 35,000USD
and actually, the first generation pony is the most reliable American car so far, almost 60% of the original Mustang still exist on the road today, which is quite rare, the second generation, is almost extint though...
