Last episode Marty was working on the MR2 which turns out to be not quite as clean as he first thought. Almost every bolt was seized or rusted, and while the body itself is in reasonable condition just about everything attached to it doesn't work. This episode the fuel tank tank needs to be removed and new coolant hoses installed throughout the car. The MR2 slowly but surely being restored to it's former glory but there's still a lot of work left to do.
Also something to note around Mighty Car Mods: we are normal guys and are not trained mechanics. We like to make interesting car mods and show you how we've gone about it, but we can't promise that anything we show you will work for your particular car, or that you won't harm yourself, someone else, your car or your warranty doing it. Please be safe, be responsible and unless you know what you're doing, do not fool around with very serious machinery just because you've seen us make it look so easy. Talk to a qualified mechanic if you are in any doubt.
