I’d echo “don’t sell one used car for another of similar value”
Unless you know yours is about to explode
Fuel economy and tax aren’t really the big costs its bills and depreciation
I’ve spent alot on a Renault Scenic (I know I should have known) but as other have said Diesel cars and cars in general can generate big bills at any time. This year we paid for a turbo and an exhaust gas valve thing. So its been painful.
No way would I trade an S max that’s working for something I don’t know about. whatever the make
Some one told me their boss spent £10,000 on a high milage volvo. He spent a fortune on repairs. Eventually he asked if a new engine would slove the problem . He was told probably but no guarantees. I think he ended up taking the hit and selling it as a non runner. The key thing here isn’t Volvo its buying a car that’s an unknown
I would never sell a car that was working unless I was emigrating
