Replace Ibiza 6L with Golf Plus 1.6?

Hello together, current fleet: – Megane 3 RS with season mark from 03-10 – Ibiza 6L 1.4 75 HP Built 2006, currently 191 TKM as winter/pendulum vehicle, average consumption 6,1L driving profile daily 2 x 65 KM to work, 10% AB, rest of the country/Bundesstraße. I took over Ibiza in 2017 from my sister-in-law and followed with it without problems 34 TKM. What bothers me: a little little performance, very loud in the interior from speed 100. My sister now sells her Golf 5 Plus, 139 TKM, Built 2007 with the supposedly robust 1.6er (not FSI). Since it is at first widely pendled, it had a Lovato gas plant installed directly when buying in 2008 – would be a huge advantage for me. Car got Tüv in 10-2018 new, 8 new tyres and was always waiting at my cousin, car master. Could have it for 3000 €. If I see it right the taxes should be a little higher and also the insurance. For that I drive naturally with cheaper car gas, but with higher consumption ch. Today, a test drive is of course a completely different feeling and much quieter in the interior. Only disadvantage, I find it personally already very ugly Currently, the ESP lamp has been shining since yesterday, that is still checked. What do you mean? I see something. I would probably want to buy it. Cheaper driving will probably not, but the comfort would be much better. Greeting
