      [super viewDidLoad];
  
  }
  
  -(NSInteger) numberOfSectionInTableView:(UITableView *)tableView
  {
      return 1;
  }
  
  -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
  {
      return [self.car count];
  }
  
  
  
  -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
      static NSString *TextCellIdentifier = @"Cell";
  
      UITableViewCell *cell =[tableView dequeueReusableCellWithIdentifier:TextCellIdentifier];
      if (cell==nil) 
      {
          cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:TextCellIdentifier];
          cell.accessoryType = UITableViewCellAccessoryNone;
          cell.selectionStyle = UITableViewCellSelectionStyleNone;
      }

         return cell;
  }
  
  
  
  - (void)tableView:(UITableView *)tableView
