What is everything i need to replace on my 98 ML320 which has 90K miles, in order for it to be an actual tune up, because i want to get the parts and do myself. Thanx

Well at 100,000 mi you should get spark plugs, coolant, brake fluid flush, cabin filter, air filter, oil filter and 8 1/2 qrts of a recommeded synt. oil. At 90k it's usually just an oil and filter. Hope this helps if it's not to late.
