should the battery be removed for 6 mouths and if so will I have problems when I put it back in the slk.

If you do not disconnect the battery, the parasitic draw from the car will flatten the battery in less than 6 months. I store my car for 5 months every winter - most winters I remove the battery and put it in a heated shop - top off charge every other month. I did leave it in the car and disconnected one winter, car did start after reconnection with no charging.

You will have to reset the radio code, the steering sensor and clock. Otherwise it's a non-issue to remove.

Also you need to deal with tire flat-spotting during storage. I have had success with inflating tires to 50psig (max pressure) prior to storage.

I would put in some gas Sta-bil. I am restoring a 1983 Mustang convertible that sat for 15 years. The ethanol in the gas formed a black sludge that congealed into flaky chunks in the gas tank,

I leave the batteries in the vehicles but connect them to trickle charger controlled through a timer to charge for 20-30 minutes each day.

Last year I found that modern Australian unleaded high octane has started attacking the elastomers in my 1969 Triumph TR6, which was converted to suit the unleaded fuels of 10 years ago - I've had to upgrade it again last month to viton rubber components. I don't know how my SLK, which is nearly 20 years old would handle 6 months on stale modern unleaded fuel. If I had to store it for that long I'd follow the procedure I now use for the TR6- drain as much as possible out of the tank and use the maximum recommended dose of Sta-bil on what's left. Refill with fresh fuel at the start of next season.
