Nobody’s going to be able to tell you comprehensively whether your car is repairable from your brief description and a few photos on an internet forum. You might be able to rectify a lot of it by fitting a sound front sub-frame (possibly a used one) but weld repairs to the associated chassis members would need to be determined by someone with experience in this line of work and might be extensive. With current labour rates this might be more than what the vehicle is worth.

I agree with Victor. For a professional assessment you need to consult a structural bodywork specialist in your Country - where ever that may be? (Rwanda maybe?) Forum readers dont know because you failed to complete the Sign-Up sections for World location and your vehicle data sections. Helpful Guidance Using the Forum
My 'gut feeling' from the photographs is that as a 14 year old vehicle this is beyond viable economic repair.

Thank You For the Response , was trying to evaluate which part are affected by Rust.
I'll look into getting a Sub-Frame and Reinforce the Damaged sections. I got 75K miles on it , i'll see how it goes.

I hear You , i look into Body work and see how it goes. The vehicle is still in good conditon selling it might be an Option.

The corroded sections do not look like parts of the subframe to me. They look like the subframe to bodyshell mounting points. Typically these areas are made from heavier gauge steel to the rest of the bodyshell and would need to be replaced like for like. The final picture shows that the corrosion has eaten right through both sides and the bottom of the box section. A proper repair would need the engine and subframe to be removed, and the mounting points to be remade and accurately aligned- very difficult and time consuming work.
The degree of corrosion is such that the subframe has almost certainly already moved out of alignment, and a bumpy road could well cause it to completely detach, in short it is in a very dangerous condition.
Victor, are these the front mounting points? I think they are. I have repaired mounting points on cars before, and it not a nice or quick job. The metro VDP in my avatar has had both the rear subframe mounts rebuilt by myself, they were a notorious failure point back in the days when they were common. I thought corrosion such as the OP has shown was almost a thing of the past outside of Russia.
YouTube channel "Garage33" and "AutoCraft" (Russian) have many videos of severe corrosion damaged cars being repaired. It's the sort of thing that used to be done 40 years ago in the UK, but apart from rare, classic or much loved cars is rarely attempted now.

Yes, they are the front mounting points, the OP mentions front engine mounts. I think you’re right about the sub-frame moving out of alignment and to rebuild the chassis would entail a lot of work. Your point about it being very difficult and time consuming to accurately align the chassis points is well founded.

I used to have my own oxy-acetylene gear and did a whole lot of car chassis repairs (also had access to Porta Power equipment) but it’s a thankless, dirty, never ending task what with chassis legs and box sections, floor panels, inner sills, outer sills, strut top mounting points on the inner wings etc the list goes on.

I’ll need to have a look at those Youtube channels you mentioned.

I'm really not sure why you are continuing to ask this question of forum Members who have only seen the photographic situation and have been fairly unanimous in their opinions so far.
Your question should have been made to the engineer (?) who physically inspected it. Virtually anything can be 'repaired' at a cost.
If you are rich enough then go ahead.
I would suggest that you read the last paragraph of post #6 again.

As Ed said, depends on the cost of the replacement, mainly the labor cost. If the labor cost in you country is small enough then it worth repairing it. But of course you should check if there are other points that need repair and the cost would increase. So without asking a quotation at a body repair shop, you cannot know if it worth or not. I cannot even give you an advice regarding where to go since we are from different countries.

Of course the parts that are rusted can be taken from a salvage car. Actually I would advice you to take them from a salvage car since the quality of the steel is better than from aftermarket.
