ATS, kwik fit. awesome gti. Any good garage, make sure they aren't using guessing games, or old hat tools.
You want laser tracking now. ATS near me are absolutely fantastic. no monkeys working on your car, they all seem very professional. but i think that is an anomaly.
Normally costs about 30-40 for a good job.
It sounds like you have had a little bump. be carefull and get all the track rods and ends checked by whoever doing the checking. they can bend very easily, and will need replacing. There not too expensive.
But make sure you do it sooner rather than later. A car that isn't tracked properly will eat front tyres for fun!
