There are a few ways to do this:
The best gas mileage from unleaded gasoline or premium gasoline depends on the car. Old cars get better mileage from unleaded.
because people thinks that new cars have a new and good features then old car and there are better mileage and good look then old models..... that why and some people buy for her impression ,, by me its my athentic answer to this question
New Cars are invented in a better technical way. Better look. and even more secure than old cars. Old cars have the bases of new cars, which means old cars were made and brought an idea to others then inventors made a better solution from an old car to an new better one. :)
old cars
"they cannot be" WHAT? It depends on the car - some cars store the mileage in various places but some cars just have the mileage stored in an eeprom chip which can be "recalibrated" and once altered there is no trace of old mileage
the old Chevy and fords were/still are the best muscle cars, they are built for speed
depends, old cars are based on power but new cars are based on technology like computers
They aren't.
the old ones r better than the new one
In past experience, I've learned that old Honda Civics and Toyota Tercels are the most inexpencive and fuel friendly cars out there.
It could, if the old gasket had failed.
The best place to buy a car for a restoration project is http://www.daves-classic-cars.com. The website has a great selection of old muscle cars ready to return to glory.
