Hi, welcome. Unless absolutely necessary don't be tempted to spend any money on changes, "improvements" and "upgraders" other than as part of necessary repairs and components, systems or parts replacement as the car is a 10 year old used car (and a VW product at that) as you may need that money for other work. Drive the car for a good while in different conditions and weather to get used to it and find what might need doing and what you like and dislike on the car and what you have or might get used to. Concentrate on brakes, steering, suspension (all three include the tyres and safety electrics ( lights, horn, wiper, blower, etc.) and reflective number plates. Then it's on to whole car (not just engine) servicing and maintenance as required, or missed by previous owner(s). With particularly stop/start VW cars the state of charge and health of the 12v battery is very important so as not to upset the computer systems or they will throw up unexpected warnings, warning lights, unseen error codes and running issues. Even if the headlights seem bright enough and well, well, before the engine hesitates to start the battery could be low enough in charge to upset the computer systems, plenty of posts and threads for all models on Briskoda about this problem. Sometimes just driving the car isn't enough to sufficiently recharge the battery and an appropriate battery charger maintainer is needed following the instructions in the car's 'Owner's Manual' and charger maintainer instructions. A very long low and slow recharge with a charger of 2-amps to 5-amps to take the battery to 100% charged is best even if it takes two or more sessions to do this. The low priced charger maintainers from the likes of Aldi or Lidl are fine for this. If you don't have the paper printed version of the car's 'Owner's Manual' then a free VWŠkoda pdf version is available from the Škoda Owner's Manuals website, reading it and referring to it can save you costly visits to garages, mechanics and auto-electricians and you will know more about the car than some long term owners.
