I'm all for progress, but I just don't see the point of buying a modern car.
In terms of progress the car hasn't changed all that much in 50 years.
The engine sits under the bonnet, suspension systems and brakes follow the same basic designs as they did in the 60's
For many years 30+ you've been able to have electric windows, cruise control, climate control and so on, I had a 1993 mondeo which Had full leather interior and all the trimmings.
The only two real differences are the engine technology, and the infotainment system.
Theses days cars are expected to be ultra fuel efficient and low polluting, and for this reason a modern car will far exceed the abilities of an older model in terms of fuel use and pollution.
In terms of the infotainment system, well what people want has moved on a lot, everyone wants bluetooth for music and calls handling. They also might want satnav, again these are really the only differences between a new car and a 30 year old car.
So yeah if you don't want satnav built in, bluetooth or a super fuel efficient engine that pollutes less then no buying a newer car doesn't make a lot of different.
I've just been down to the fiat dealer to pick up some bits I ordered an had a look at a new punto brochure and I note that the fuel economy figures and CO2 are really not that dissimilar to fiat punto's from 15 years ago.
So in all honesty they've not moved on a lot other than some bluetooth.
The main reason people update their cars is either a want of a newer model or because their old car is wearing out.
your 10 year old punto, regardless of mileage has seen 10 winters on UK roads and 10 Summers in UK heat. that still takes it toll on parts which will eventually need replacing.
