Ten year old cars dont just mean dated technology and less power. It means worn components and just changing the brakes and other regular running-gear stuff and giving the engine a freshen-up will not prevent it being less efficient, on performance and handling, compared to when it was new or almost new.
A USA motorcycle magazine did some research on this. A Honda Super Blackbird was dyno tested new and then at 5000 miles, then at 10000 and later at 50000 miles.
Serviced as per the handbook, it gave the most power at 10000 miles, but 7% less at 50000 miles.
Also, the handling had suffered and lap times were poorer.
