<prompt> Human: My current vehicle is an 1998 Infiniti QX4 170k miles SUV Ive had this vehicle for 9 years now and there are quite a few fixes that needs to be done. Im trying to figure out if my truck is worth repairing or is it time to get something newer? The vehicle is worth 2500 on kelly blue books but probably nowhere close with the repairs that I need.My right CV axle is starting to go and have an estimate for 500.My brakes and tires needs to be replaced fairly soon. 400ish?My State farm In-drive shows in Vehicle X-Ray Diagnostics that my powertrain is in need of service but I havent gone to check with a mechanic to see what is the exact issue.There are multiple oil leaks and I have repaired parts of my muffler but other parts are rusty and are being held by wire hangers due to salt.I get around 14 mpg city, which is pretty poor but I live 1.5 miles away from work and 5 miles away from school which I will attend twice a week in the fall. So a higher mpg vehicle wont save me that much. My concern is that I have no idea how much longer the engine will last and I dont want to dump money into a car that might go out at anytime. Any advice would be greatly appreciated.  <response>: Those are some really cheap tires if you can get them and brakes for 400.. You are more likely looking at 4-500 for tires alone. The brakes are not that hard to do depending on what you mean by needing brakes. Padsrotors can be had for cheap and done with 40 in tools total. You may be able to do them for 120 or something on your own depending on if you get new rotors or get them turned by a shop. If you need calipers that will probably make it 300 for brakes.DeathToCanadians pretty much explained it. You could put on some used tires and a junkyard cv and cheap brake padsrotors etc and get some more life out of it.. Unless you dont want to keep it...
