Hi. Thinking of making a Karoq my next car but struggling to figure out if the one I'm looking at is fairly priced. Here's the link on Auto Trader: https://www.autotrader.co.uk/car-details/202310243278110 I'd be stretching myself to afford it but it does seem a particularly tidy example. My only concerns are: 1. It's 6 years old. I'm hoping to get at least 5 years of reliable motoring out of it. Is that realistic? 2. How's the 1.0 TSI engine? Seemed pretty capable during test drive but would appreciate opinions of other owners. 3. It's had the water pump changed by the previous owner but I don't know why. Is this a part that Skoda recommends is changed at certain intervals, or does it maybe indicate a serious issue (overheating etc.)? Thanks in advance for your help!
