We bought a 54 plate Mazda 6 estate, 2.0l petrol, last year. I can’t fault it. It drives like a new car, not a single squeak or rattle, everything works perfectly, it’s got cruise and climate, and a cavernous boot. It’s not the most inspiring car but it shifts if you rev it and it’s comfy long distance. We only do 6k miles a year so I avoid diesels like the plague (I can’t stand em anyway) and as we don’t do many short journeys cruise and a comfy seat is more important than fuel economy.
I’d have another like a shot.
Pretty much this though I had a 56 plate Mazda 6TS2 estate in 2ltr diesel format for 9 years and despite driving it like I stole it it was utterly reliable, the garage that bought it even said it drove really well and assumed I had not driven it like a pensioner which was the main reason why modern TD diesels will survive. If its designed to go to 5000rpm then take it there 😀
