Think its just that our cars are now 10 years ish old.
To us, they are well worth a few thousand more but to the public at large they are just old bangers.
Not old enough to really get to the Classic Car stage yet, but give it a few more years.
Just have to look at old Mercs, Jags etc. £35 - £50 thousand pounds new, 10 year old £2-£3 thousand. Some of those look nice.
