I could only speak for the 4x2 MT LS. Good thing I managed to keep my receipts for future reference.

1st PMS: 3,478.27 Change Oil and Oil filter. Free Labor
2nd PMS: 2,226.83 Same as the above.

For the succeeding PMS, I inquired on the prices and the guy showed a paper with the following figures. I forgot to ask though if the price of labor is inclusive.

10k PMS: 6,020.27
15k PMS: 4,788.71
20k PMS: 10,371.15
25k PMS: 4,788.71
30k PMS: 6,567.71
35k PMS: 4,788.71
40k PMS: 11,662.78

Please take note that the above prices are based on what I saw in their list and you know them, they could change the figures anytime so it's still best to ask them first for more accurate figures. Hope this helps! Go Dmax!
