A lot of older stuff is flippin rubbish to drive. I’ll count my cortina in this but owning one is more than just how it drives it’s how it makes you feel and and an experience that’s different from modern stuff , which all drives the same.
I am of the age (60's) where a modern pile of crap is easy and comfortable to drive. But would I miss driving the MG roadster in the summer months, you bet I would. It's uncomfortable, at times unreliable, but just puts a smile on your face when you blast down the M1 towards Meadowhell in the outside lane past all the saddos in their big standard boxes of shite.
Just get out there and enjoy it, it might never be the daily drive you wanted, but fun and enjoyment is what it's for. Trust me.
