I have also favoured cars with big engines, as I believe that they won't have been thrashed.
I would agree with you on that.
I have always tended to have cars with big engines. More relaxed, less strain, smooth effortless power usually wrapped up in total comfort with similar performance to a lets say a sportier model.
This was evident in my service days. Panda cars (ranging from 1.1 Mk1 Escorts when I started in the 70's through to Astra 1.6 Diesels) were often knackered within a couple of years or 45 - 50,000 miles, whereas our Traffic cars (Granada's, Jags, Senators, Omega's but excluding the SD1 Rover) would easily cover 150,000 miles plus before they were taken out of service despite having being driven hard.
Even now, I think that still rings true regarding engine sized, despite the fact that my next car is likely to have a 1.5 turbo, but then technology, especially engine technology, has moved on somewhat over the past few years
