After watching your video. I bought a used 2007 Honda crV with 161,393 Miles. Automat. 2 weeks later loud noises and car wont start. Mech. said the exhaust system ,undercarrge is all rusted out. Should I sell it or is it worth fixing the cost to fix is almost 1k dollars .please help I bought it because you suggested old Hondas are better than new ones. thanks
Older cars, including Hondas, are often built better than newer models because build quality continues to decline. This does not mean you can go out and buy a used car without having a mechanic inspect it, you should always have a pre-purchase inspection done. A buyer should have a mechanic inspect a vehicle before purchasing.Mech. said the exhaust system ,undercarrge is all rusted out.

Mech. said the exhaust system ,undercarrge is all rusted out. Should I sell it or is it worth fixingYou can't really "fix" rust unless you replace the metal so I'm not sure what your mechanic is suggesting you/he do. Any pictures/videos of the rusted areas could be helpful.. the instructions here >READ THIS FIRST
The fact that the CRV is already 17 years old + the purchase price + your mechanic wants you to spend another 1K.. Much depends on how much you paid for the CRV and just how bad the rust is.
(Note: surface rust on the exhaust system is completely normal.)
@hixster Yeah I would like to see some pictures too.
I would be curious what stopped it from running.
Exhaust systems are not usually that expensive for an aftermarket one. I put a cat back exhaust on a Pontiac vibe for about $400, with a friends help for about 2 hours.
Rust can be a killer, but I don't agree with people that say you can't stop it. If you are willing to put in the work, you could possibly deal with much of it yourself. I live in upstate new york, and twice a year, before and after winter, go over the underside and deal with any rust and treat it so it won't come back for a while. With rust, the worst thing you can do is nothing.
@nlord not addressing rust surely doesn't help the problem any.. Hope it's only surface rust. Living in the salty northeast as you do, don't you have to become a rust expert? lol
@hixster Sadly it seems that many people just ignore it and buy a new car. A good many will have it done by experts that will stay on top of it each year, like it should be done. I can't afford to buy a new car, so I put in the work to make sure I keep it in check. I have even helped save some friends cars that they thought were doomed, and though the rust did some damage, the car isn't getting much worse now. I have contemplated doing it for a side job, because so many times it could be removed, and protected fairly easily. It is just something you have to stay on top of, most people won't do it.
@nlord Some techniques are very helpful in slowing its spread but I've never seen anything stop embedded rust. Nod to you for helping someone with rust issues as anyone that's ever done this knows, it can be a lot of work
@hixster when it is bad enough, I hit it with a wire wheel and that pretty well knocks it off. When it is not near the exhaust, I prefer cosmoline, it smothers any rust under it, and is self healing when it is warm enough. Of course, you don't want to put it on any flaking rust, that is what the wire wheel is for, or wire brush etc. I go with rustoleum if it is near exhaust, or it is very light rust that I can clean up nicely, then give it a few coats of that. I am about to hit the rear diff of my GX470 with rustoleum 600 degree primer and paint made for engines specifically, I think it will go well on a rear diff. I use multiple methods for different conditions that I have learned over a few years.
