I will be leaving the car for 3 months. Do you guys think that I should get the oil changed before I leave? Any other suggestions?

 

Sell it and buy a new car when you return?

 

Whyyyyyyy? I will be loosing more than 5k renewing this car.

 

No. What you probably should do is, get a slow trickle on the battery, put the car up on jack stands so the tires don't get a flat stop. Cover it with a good car cover that has padding inside of the material so the paint doesn't get scratch and a material that breaths or allows air to circulate. If the car was stored for a longer period there would be a lot more to do, but for 3 months the above procedures will be OK.

 

hmm i think i would not be able to put the car on the jack stands because i am parking it in a public garage people might mess with the jack stands or something. Should I get some air off from the tires so that they would not get flat spots? For the battery, my car is still under warranty so I can get the battery changed for free. Should I put the trickle? Would the battery getting finished have any harm on the car?

 

NO, don't let air out of the tires. If you can't use stands, I would over inflate them by a couple of pounds. I had my battery go when the my car was under factory warranty and I had to pay for the replacement, pro rated of course, as the batteries are only warrantied for 2 years. The batteries are prorated for the two year period, after two years however you pay full price. They did not charge me for labor. If you mean will a trickle charge overcharge the battery, usually not, if you have a good battery trickle charging device, it should have an auto trickle setup, when the charge get low the trickle turns on. www.autosport.com has a couple of these charger, jumper and air compressor combination devices, their not cheap but sell a quality products. But IMHO, Mercedes batteries are junk. I've had my car a little over 3 and a half years and I am on my third battery. The first two started leaking. This one has been in almost a year, so far so good?
