Just a typical day of work at SPS Automotive Performance in Hong Kong.
When most people take their car to a garage they are most likely going to see other run of the mill cars. Maybe if they are lucky they will come across a higher end luxury sedan or sports car in the $50k-$100k range. So you could probably imagine what it would feel like if you happened to walk into the SPS Auomotive Performance Workshop in Hong Kong as the person in this video did. On hand were 3 Pagani Zondas, 3 Huayras, Gumper Apollo S, a Lamborghini Countach Quattrovalvole and an Aston Martin Vantage from the 90s.
Not sure if any of these cars belonged to the person filming, but odds are that the YouTuber wanted to get some up close footage of rare exotics without having to pay an entrance fee.
