i need a new classic engine and most of that stuff, transmission, wheel components like breaks etc, and paint job and fixup interior.
Ground up restoration is an extremely expensive business to get into.
If I have a customer who wants a classic Mustang build, I always meet with them to discuss exactly what they want. A lot of your reality TV shows make it seem like this is a 5 minute deal. It isn't. It takes hours, sometimes days and multiple meetings, to hash out exactly how the finished product should look and perform. @ChuckTobias is not wrong...I've done many builds where just the paint is $15k. It all depends on what the customer wants done.
Of course, there are many other things to consider such as whether or not they want to keep the car numbers matching. If so, the build gets more expensive because now you have limitations on what you can replace with new parts and what you MUST reuse. And original, classic car parts...Mustang or otherwise...can be hard to find and expensive.
There's not really an economic way to flip classic cars as it sounds like that's what you want to do. The sheer amount of labor to do things the right way....I have a full staff of expert fabricators, painters, etc. and it still takes a lot of time to get a job to the point of completion. If you are looking to do this yourself, I'd recommend fixing up more modern cars unless you have the skillset for custom fabrication, body work, paint, rust repair, and electrical wiring.
In answer to your question, it depends on what motor you have, whether or not you want to change it, what trans you have, if the paint is good. Cost-wise a lot of my builds on classic Mustangs with the 289 V8 run in the range of $80k - $120k finished, but those are very vague numbers. Just adding airbrushed artwork can easily tack on $10k - $15k more. Moving to a bigger motor? $15k - $20k more. If the frame has issues? No telling. I have had cases where I had to get a donor car because the customer car was too far gone and I needed to use a new frame, axles, etc. Some of those have been $200k+ builds that took 3-4 months to do.
There is money to be made in this business. I live comfortably, but I started with nothing and it took decades to get here. When I started, I stayed away from ground up jobs and anything that needed major repair. I am one guy, and those jobs were too much. So yeah, you start with jobs that require less work and pay you less money, but that you can do yourself. Then you work your way up as you go. Eventually you get a shop, and equipment, and then staff, and repeat customers. But this happens over many, many years....not overnight.
Hopefully this gives you some insight on how this industry works.
I have all tools and paint (artist my self) i need to know where mechanical parts are sold like v89 engines and transmissions. Also im going economically how can i don't want "all original expensive parts" just good inexpenisve parts and aftermarket things for a classic mustang.
Well, online classic parts shops are a good place to check, but your be well served to visit some classic car restoration shops in your area. A lot of times they have parts that are for sale and at reasonable prices. I've bought all kinds of things from "competitors", and them from me. But it depends on parts. Things like transmission, engines, big ticket items I'd go that route. But weatherstripping, door panels, etc. can be found online with a little research.
how is Auto rack AC or CJ pony?
CJ Pony is a very good site. I've bought a lot from there. Autorack....not so much.
Benson how you want to make them it can cost a small fortune if you want to go original equipment or if you want to modernize them with disc brakes and stuff like that it can get very expensive
I want to do classic cars economically and fix them up like that.
I talking about doing them like in your video. How much could i cost to do the stuff i'm thinking about. https://www.youtube.com/watch?v=aIXIHDfoQw0&t=265s
To do it right costs a huge amount of money. Heck, you can easily spend 5 figures just on a decent paint job.
Just as Scotty says, if you are looking for all OEM then hope ya got deep pockets, as other members have probably already mentioned before, good luck getting anything for the car, parts will not be plentiful and if you are looking to buy "new engine and trans" haha you need specialists for that work. Pretty sure someone mentioned also that a good paint job could easily cost you $15k alone. And that said, Trim pieces will be even worse to find OEM. I have a 1987 BMW I am restoring atm, lemme tell ya, I've been looking for a very specific trim pice for months. I don't even care if it be in good condition anymore cause I be sanding it down myself. People here in cali be crazy trying to sell rolling shells for 3-5k -_-
Like to buy a new classic engine, transmission, fix interior and wheel componets e.g struts, breaks etc.
Then you would be spending a small fortune on a classic mustang people like them and the prices lately have gone sky high
This feels like deja vu.
It really depends on the condition of the car. If you have one in decent, running shape, expect to spend $60k - $70k fixing it up. But those are ballpark numbers.
If you have rust, it will cost more. If it needs paint, it will cost more. If the frame is damaged, double to triple the price.
Parts are scarce and expensive. If you need big ticket items, like an engine or transmission, it is going to cost you a small fortune.
And everything @bruceREE said is right. Still.
