2016 gearbox worries

[JB33]

Hi,

I was quite set on buying a 2016 Soort Nav 2.0 from a private buyer, full history and 41,000 miles until I read that Mazda have a various amount of gearbox revisions for synchro problems. It totally out me off, should it? How bad are they and would it out you off? My budget doesn’t allow for a new one or even a 2018. I fear parting with my cash then being stuck with a car that needs a new box.

Thanks :-) .
