I?ve been doing car flips for years. Mostly 40s through 70s American.3 years ago I was doing 380-560sl Mercedes because I had a contact in Germany. Cars over there rust because of salt so he bought a bunch from me. Normally I got $1000 over my cost and he did the shipping. The best one was a 93 SL 500 AMG with an add on twin turbo kit. The alternator went out and the owner got tired of trying to change it outside in the rain. He gave up and put it on Craigslist 4 minutes before I saw it. Wife and I loaded up the trailer and headed there. He was asking 3300,!!! I eventually negotiated 2300. Loaded up and headed home,fixed the alternator in about half hour a went for a ride.All good.With that twin turbo Mercedes engine spooled up I was really surprised at how strong it pulled.Sold to my German buddy Rollin for20,500. He drove it for a couple days and sold it to a local guy for 25,000 USD. I pulled back from cars and am now concentrating on roughly pre 87 street bikes. Lot less buy in upfront but won?t make as much at the end. Motorcycles are cheap. Lots of fun though.
