I've been sold ever since....and yes I change my oil every 5,000 miles. Its just my opinion but I think the oil maybe able to last 10k but the factory oil filter was never able to last that long....just my 2 cents....
Where did you get those headlights from?? or did you do them yourself??
I have a black 4runner and I agree that its hard to keep clean, luckily I work at a dealership and get details dirt cheap....
