Here's a new commercial recently posted by Ford Europe for the Focus RS and you can see the driver floor it in order to reach 0-100 km/h in 4.7 seconds.
Not sure of anything new but there is of course the option to buy something on the used car market, modify it and go just as fast or faster than the RS.
Indeed, but fact is it's an option that some folks will want to weight out, something other won't want and instead just want something new. Many perks to buying a used vehicle especially if you're a value minded person.
Owning a vehicle off warranty or still with a portion of its warranty term to go can still be worth it, just have to know what exactly you're getting yourself into before making the purchase. With that, you're better off.
I can't imagine that being the typical commerical you'll see, it's more of a promotional video directed to a very specific audience, like us. More along the lines of what i'd expect to see on Ford's website than off of it.
