We've done over 100,000 miles in seven years in our 2005 Honda Stream and we will need to spend some money on it in the near future. However, rather than spend it, we are looking for a replacement.

Diesel is preferable, as is reliability, and we'd rather have something more interesting than bland. We're aiming to buy second hand.

Ford's C-MAX or S-MAX seem interesting, but I'm put off by their relative lack of reliability. Mazxda 5 or Volkawagen Touran are possibilities, but I'd be interested in your thoughts.
