Morgan's are generally very slow compared to Caterhams, they have appalling handling and road holding compared to Caterhams but have bags of character and are much more of a classic car.
I've had, many Caterhams, including a 320bhp monster but still hankered after a Morgan to cherish. I really found that Caterhams were great when driven fast but annoying when conditions didn't allow that. Morgan's give a lot of fun at more normal road speeds and are more useable.
