Pedro, low miles, er low kilometers, sounds like a good find. First the transmission: should be serviced every 30,000 miles, so you are right about there. Chage the filter and the pan gasket, and be sure that the torque converter is also drained. Best not to neglect this if you plan on keeping it for a long time.
Hard start? 2-3 seconds of cranking time would be considered normal, the fuel pressure has to build up. If it was my new 7-8 year old car, I would replace the fuel filter and add a can of 'dry gas' to be sure there is not any moisture in the fuel tank, especially because the car has been sitting around alot, I put that many miles on my car every year! It is also a good time to check the spark plugs, good chance they are the originals, Bosch only please....
