I was very close to changing my Vitz 2018 for the GLX CVT, but thankfully better sense prevailed and I stopped myself. It seems to be a good decision for now, since there are a lot of teething problems with it. Hopefully they will be sorted out over the next few batches of production and we will have a better car as an option in the market.
I have used 3 JDMs (over the past many years, and the overall experience regarding quality and reliability has been very good. Maybe due to the fact that I got al three from reliable sources, who weren't expected to cheat me. Also used many PKDM's and Suzuki's were the worst. Toyota, Honda and Kia were much better, some close to JDM level quality and reliability.
