Does anyone know where I can store or park up a car for a few months?

There are two recently opened airport parking businesses opened which may be worth a try.

one is next door to the TOT office at the Robinson intersection.

The other a little further away along the mahidol the down the road across from Mcdonalds, Suksawad is on the corner, airport parking about 400m along next to the Arise development

Is there a  friend you trust that can look after it for you and give it a quick run about every now and again?  if only to keep it warmed up for your return and the engine oil circulating. It will not do it any good at all to be stationary and not run for many months in this climate. 

I think across the street from KSK, behind Buddy's, you will find a car storage 2/3 deck garage. All covered, seems v safe and may be watched. Worth a recce.

More than 10 years, cars, bikes left for up to 6 months for work. No issues other than slight mold in car. Easy cure with vinegar.
