Hey Ash, something to bear in mind is that the majority of us on here will typically do a load of research before buying any car and then just buy the one nearest to home (normally after a few beers), find out it’s shite and then flog it for something completely different in much less time than this thread has been going.
I can honestly tell you I’ve never looked at 6 of the same car before buying. 2 is my tolerance level before losing the will to live and handing the cash over. I’d rather spend time fixing what I’ve bought than chasing a unicorn.
Most of us on here recognise that sometimes you need to tread your own path with these decisions. Nobody here can offer you the reassurance you might like. Any used car purchase is like rolling the dice in Vegas, diesel or petrol.
Certainly in the UK, buying cars is ‘cheap’ and easy. If it doesn’t work out, no worries……. Next…… Are things that different where you are? If you buy one and it’s not right, so what? Just sell it and get something else. Even when something is catastrophically knackered somebody will still buy it.
I’ve bought plenty of cars in the past that everyone told me not to buy. I’m still here to tell the tale, not filed for bankruptcy just yet and I’ve bought countless cars on eBay sight unseen.
If a diesel is what you want, get one. If it all goes utterly tits up, suck it up and make it a great story to tell your mates.
