Take care of certain things like:
1- No matter what, never wash its engine.
2- Be careful while driving on rough terrains, suspension parts are expensive and not as sturdy as hondas or toyotas.
3- Keep a track on coolant level and all other parts of cooling system, change when its necessary. Once the engine heats up the gasket is probably gone on this model, and I have never yet come across any trustworthy mechanic who would restore the engine back to its original specs without messing it up more.
4- No wiring jugaars.
5- Never ever do these things; Remove thermostat valve, running the fan direct rather than on auto or use water in the system.
6- Never use 20w50 grade oil.
There are other things as well which probably apply to all the cars irrespective of make or model.
Maintain it periodically is simple, just follow the owners manual. Do not experiment with oil grades. Use genuine filters. Replace all the fluids when necessary.
