If I were you, I’d book some test drives.
I’ve had a Mondeo and a couple of Passats, nothing wrong with the Passat but the Mondeo was just all-round better. The new Passat looks very nice though, I’ve not had a play with that one.
My experience with Skoda hasn’t been favourable. The last Octavia I drove (a few years ago, mind) had uncomfortable seats, and when I ventured into a Skoda dealership recently to discuss potential leasing I got a complete cock of a salesman, a cockney wide boy with sales patter straight out of the 70s. Of course, that’s an anecdote from a sample size of 1, the rest of them could be wonderful.
