No worries, I'm sure you won't go wrong with a high spec TFSI... they're good engines.
Do some research and don't be afraid to travel around the country for the right car once you know the age/spec/mileage/colour you're after.
Often cars can be a bit cheaper up north too. If you do decide on travelling for the car though, make sure you do the deal before you go on the phone. Once you've travelled 100+ miles for a car - the dealer will know you won't want to go home empty handed.
