and buy which one? Please suggest.

all cars have their issues, just get something new or a well maintained fairly used. Go with a sound and experienced mechanic for inspection and enjoy your car for the years you wish to use it

yeah. I thought the guy I quoted would mention a particular car, then I would tell him the bolded.

Meanwhile I have been using Peugeot 407 since 2017. If I sell It, I will buy another 407.

Bro is it manual or automatic?

automatic, then later converted to manual

1Alex:
automatic, then later converted to manual

why did you convert to manual

EggSauce:
why did you convert to manual

alot of things are connected to the gear. Everything that concerns the tyre is connected to the gear. When the tyres are worn out, when the ABS sensor on the hub is damaged, when the tyre has a puncture etc, they all report to the gear making the gear to get stuck on speed 3. This is not a malfunctioning of the gear but it is designed for the driver's safety. When the vehicle develops any of the issues mentioned above, even if you install a brand new transmission, it will not work till you fix the issue.

So to drive my car with a worn out tyre or to drive even with bad ABS sensor or drive even when the tyre is punctured, I decided to covert to manual transmission. And now this is July 2024, I am still enjoying the ride.
