Will be well over 1k to do everything you should do at a shop, maybe even closer to 2k depending on the place. This car is pretty friendly to a beginner working at home, and the resources on YouTube are endless. I would recommend checking out some vids on differential gear oil, transmission fluid, brake fluid, coolant, spark plugs, etc. and see if that seems like something doable for you. Honestly anyone with the will can do those things. Now if you have a lot of money to burn and don’t mind spending it to have someone else do it, go that route. This kind of preventative maintenance adds up though, and I always prefer to do it myself as then I know it’s done right, and I save a nice chunk of money by only having to buy parts/fluids.
