How expensive is a Lexus IS 300 to repair?

I currently have a 2002 BMW 325 that drains me when something goes wrong, right now it is $550 for my hull assembly (Idk.) Anyways, besides tires and oil changes, i want to know more about brakes and suspension and more in depth parts to have repaired.
Looking at a 2004 Lexus IS 300 with under 65k

I have a GS 300 ‘99 Lexus..and found lexus dealerships cost ALOT..i would suggest if possible take it to a toyota dealership..i have experance an almost fifty percent discount almost in price. Oil changes and what not just goto a mom and dad shop or even place like midus..they charge the normal 10 to 20 dollars.. Other repairs just depend on the issue.Such as i had my altanator changed costed me 120.00 dollars thru bucky’s Lexus of seattle wanted 400.00 some dollars Well hope that helps some..
