I bought a 93 Lexus GS with about 150,000 miles on it from someone who didn't have any service records for it. I have had the car for about 6 months now and still have not serviced it with the exception of an oil change. A mechanic told me it needed a tranny, brake, and power steering fluid flush, A complete tune up, Upper and lower radiator hoses, Drive belt, and Possibly a timing belt.
My question is this: should i let this mechanic use his own fluids in my car or should i supply him with authentic toyota products to put in??
And also i have no idea when the timing belt was last replaced, should i go replace it anyway?
