In the below links are some of the things Members have been doing to their cars and some of the areas that need work. If you cannot do or unable to learn to do most of the jobs you most likely will not be able to afford the Car you want.
As an example to replace a Timing Chain there is about $260 special tool; the Timing Chain itself is about $150 and the Timing Chain Tensioner Rail is around another $50.
If the Rubber parts have not been replaced before:
Rear Axle CV Joint Boots
The Front Suspension is mounted on rubber parts- see replacing the Lower Control Arm Bushings and Upper Control Arms in the DIY Links.
Replacing the Lower Control Arm Bushings requires that you Make, Rent or purchase a $189 spring compressor for the Front Springs. The typical Spring Compressors sold in the Auto Part Stores for workingon Struts are not safe. I know because I tried it and twisted up my Spring Compressors. I ended up making a spring compressor.
Oil Cooler Hoses- Read what to do if the Oil Cooler Nipple Strips when you Remve the Hose (this happened to me).
No U-Joints; it has rubber FLex Discs
Motor and Transmission Mount replacement
And so on....
