Unless you have won lotto or have easy access to lots of cash, just upgrade your car. I have always had cars 15-20 years old+ through lack of cash and it would not be unusual to have to spend $300-$500 to get it through a warrant, even with doing many fixes at home. 2 vehicles means 2 wof and reg to pay for and 2 lots of fixit bills. Unless you can borrow a car when you need to take the girlfriend out or buy big stuff, then a motorbike is the most economical of course. And the coolest. And the deadliest.
