Congrads. I've owned 3 myself prior. Simple and easy to work on. You basically will only need a 10, 12, and 13mm wrenches and sockets. Everything is either phillips or those size. You'll have to trim the door hinges to be able to remove the doors like a Jeep. Rust can occur under the carpet anywhere but mostly in the rear floor, behind the kick panels of the rear wheelwells, under the windshield wipers, under the plastic cover under the doors, and in the front wheelwells. Best thing would be to give it a good bath under the flares and plastic covers. All wiring will be water tight connectors. To get better highway accel, there is a trick to do with the carb. Some tube replacement. There is still lots of following for these things. If you need to flip it, you probably wouldn't be sorry with the mileage on it. There are lots of Sami/Zuk forums and clubs out there also. Do a little web search to locate something near you.
They are small, light weight, fun to drive on city streets, suck on the highway, bounce hard on the street, noisy, slow, and fun to drive stock. One location near me on the highway, there is a swoop in the road. Driving the Sami at 65mph felt like I got some air.
