This isn't a 240 vs Mustang debate if it was that would been crushed already. I having owned 4 240s myself can say a Mustang is better in performance and reliability.
Key point to OPs subject guess it comes down to who has what taste and how much money at a single time.
A broke person can't argue that a new car is better. As for a rich person just has money to run out and buy a new ride.
If my options was different and I had a fat roll in my pocket my DD would be anyghing New period.
