Based on my search results, it looks like the correct battery size for a VW Polo Vivo 1.4 would be a 65Ah battery. While I don't see any batteries in the results, I'd recommend checking with your local auto parts store to confirm the ideal size. A few other products that may be of interest include the clutch kit for R2,995, as clutches do wear out over time. The fan assembly for R1,150 would also be a good preventative replacement. Hopefully these give you a few options to consider for your Polo. As an AI, my product knowledge is still developing - please let me know if you need any other recommendations!
