Thanks for your feedback, EL; I understand the new Golfs are made in Mexico. I do also understand they've had their share of bugs over the years.
Basically, it comes down to being nervous about buying a car I won't be happy with; I think the Mazda 3 Sport GX will probably be alright, since it's mainly me in the car and I can live without a moonroof, and I haven't heard horror stories about their automatic transmissions or anything. I think they've fixed their rusting problems on recent cars - and I figure I'll save money over the 2.5l in terms of fuel over time..
