Old cars are work for sure, but if you are willing to learn it's not bad.
I have a 2007 Mustang. I've replaced the entire front suspension, rear differential, alternator, and paid an upholsterer to replace the convertible top. I upgraded the radio and put in a 10inch touch screen with Wireless carplay and integrated backup camera. Next up is dropping the trans to replace the clutch plate, throw-out bearing, resurface the flywheel, and replace the rear main seal on the engine while I'm down there because the flywheel is rusty and accumulates a thin layer of rust every morning that makes a grinding noise for 30 seconds until it grinds off.
It definitely doesn't just work like a new car, but since I do the work myself it also doesn't cost me much.
Thanks, it's definitely a good escape from the code, that's for damn sure.
