Thanks for the reply Paul,
As far as mileage, it has nearly 127k. My son bought this car back in 2003 from the original owner and it had all the maintenance receipts, etc. He gave it to me about 5 years ago. He, like myself take good care of our vehicles (ie. oil changes, transmission oil changes, etc.), it never gave me an ounce worth of trouble except for some motor or actuator that activated the vent controls located behind the glove box. Oh, forgot, Lexus did do some exhaust replacement and changed an O2 sensor this fall. To the best of my knowledge that is it. My other son is a master mechanic at on of the dealerships here and usually helps me with all of my mechanical problems. As for AAMCO, it cost nearly 4k with a three year warranty. I can't think of anything else.
Thanks for the prompt reply,
Bob
