Don't do it.
You'll never want to go manual again, and you'll be limited to either VW GTi or another FR.
The car screams "modify me" every time you turn the key.
And you're liable to lose your current relationship because of the time spent polishing and waxing your "baby".
Or do it, and get one of the best cars made for the money
make sure it's got Full SEAT Service History (FSSH), if around 60k miles, ensure that cambelt has been done.
Check tyre wear, and any leaks in the engine.
Have noise proofing under bonnet replaced (if mouldy). Make sure they do a full oil CHANGE.
AND...most important. Test drive it warm AND cold and make sure the DSG doesn't judder at low speeds (traffic jam speeds).
