Are todays cars more reliable then those cars built 15 years before?

my question is, are they more efficent and reliable interms of number of times they have to be serviced or visit the garage.

I have Nissan Bluebird 1992, i hava had it for 4 years, in 4 years i have only taken it to Garage 4 times for MOT only.

Before this car i had ford Fiesta si 1994, it was faultless, i had to change it beacause it had 3 doors and i dont like 3 door cars.

I am planing to change my bluebird this month because i need a smaller car as i cant afford Petrol on this car.
